    I thought this Paper B was surprisingly easy - so easy in fact that I'm very worried that I missed something major...

  2. Well that was a lot nicer than Paper A, that's for sure...

    ReplyDelete
  3. Clearly drafted by a different person to Paper A (thankfully)

    ReplyDelete
  4. I also think it was rather straight Forward and everything fell into place nicely. However, with Claim 5 and 6 I am Not entirely sure...

    1. Claim 5: I merely amended "connected" to "connectable" based on Guideline F IV 4.14.1

      Claim 6: I merely reformulated as dependent on Claim 5.

      Delete
    2. I did the same for claim 5, but introduced the recess and the connection of the support columns (sorry, No Idea was the English wording actually was) to the device...

      Delete
    3. I ended up moving claim 5 to be dependent on former claim 6 (now claim 5), and changed the specifics of what was snapping to what to get around the disclosure in the prior art.

      Delete
  5. Was the recess inventive? Could not find anything else. Also the communication stated that the subject-matter of cl. 2-5 (the recess being in claim 3) "does not appear" to be inventive, but no concrete prior art references were given to back it up.

    1. Was there a technical effect associated with the recess? If the answer is yes, then it is inventive.

      Delete
    2. I agree the recess was a bit iffy from inventive step perspective - realistically it seemed hard to argue that the prior art trays wouldn't achieve the same effect: contain small amounts, leak large amounts, and invariably leak from the front due to the lower wall! But there seemed to be unambiguous novelty at least, for the recess, and arguable IS on the basis of "directing" the water in a certain way. I did shite myself a bit at the end of the exam when I remembered the examiner had essentially raised an IS objection against claim 3 - but I think we all know that kind of broad-brush IS objection is open to argument.

    3. Recess on its own is not novel in view of the opening in D2.

      Delete
    4. Yes it is because the recess is in the front wall

      Delete
    5. the front wall in D2 is one of the 4 sidewalls....recess on one of the sidewalls, so can also be on front wall...yeah that was a bit confusing to me at first because the application distinguishes between front and side while D2 doesn't.

      Delete
    6. Yes it is, the recess was specified as an outlet but D2 holes were water tight and sealed during use

      Delete
    7. In my view, it is essential to define height C as being lower than height A. A front side that is lower than the other three sides inherently creates a recess at the front. If the recess is not defined by specifying a height lower than that of the front side, the claim may not be novel over D1, D2, and D3.

      Delete
    8. I agree with the above poster that the recess was required to define height C as being lower than height A, changing the client's added section to "such that" and framing it in terms used in the application.

      The side holes in D2 were for handles etc and were sealed in use.

      When you add in the difference in height and the such that part all of the prior art teaches away from claim 1.

      Delete
    9. Specifying what the recess does i.e. the function, makes it inventive but not novel.

      Delete
    10. It's already novel Stefan. A sealable opening is not a recess with a specific height. The recess is not disclosed in D2. D2 is just telling you not to try and generalise the recess.

      Delete
    11. Stefan, how can the feature be inventive but not novel??

      Delete
    12. agree with above poster? how have you arrived at something being inventive but not novel!?

      Delete
    13. I obviously misspoke. I meant the function of the recess is relevant for the inventive step not for novelty. The fact that a side wall in D2 comprises an opening takes away the novelty of a recess in the front wall in claim 1.
      The figures in D2 show the opening on the lateral walls but the description of D2 indicates it can be on any one of the 4 side walls without making any disctinction of whethere it was a front wall. Super tricky stuff :/
      I admit I wasn't sure whethere including the C height is necessary but my reasoning was that i prefer to end up with a slightly limited claim rather than with a claim that is potentially not novel.

      Delete
    14. In fairness I don't think including the height really limits it. The only other interpretation is that the recess goes backwards in to the tray for some reason which wouldn't solve the problem.

      Delete
    15. I tend to think the recess was novel over D2 because it was in the front wall. In principle any wall in D2 could be considered as a front wall, but claim 1 also specified that the front wall is lower than the other walls. So the combination in claim 1 defined that the recess is in the wall that is lower than the other walls. A recess in the lower wall did not appear to disclosed in D2.

      Delete
    16. What about the case where height C is zero? This would still be possible with a claim that specifies height A to be larger than C, but would not achieve the intended distinguishing between condensate and leakage...

      Delete
    17. Stefan I still disagree. Claim 1 required that the front wall was shorter and had the recess. D2 had an opening but clearly not in its shortest wall, so D2 is not disclosing the recess

      Delete
    18. See my comment above. D2 had the opening in the sidewalls, which can be a front wall in D2. The figure in D2 is diabolically misleading.

      Delete
    19. I included that the recess is an outlet in claim 1. D2 does not disclose an recess being an outlet, since it is a ⋆༺☆water retainer☆༻⋆ used for ☆~retaining~☆ water. Does not make sense to have an outlet in such a product.

      Delete
  6. Easy stuff. Recess is clearly the invention, and it’s inventive over all three prior art.

    ReplyDelete
  7. I went for the recess and think it was inventive in view of the documents...

    ReplyDelete
  8. I did not find particularly easy, but manageable compared to paper A.

    ReplyDelete
  9. I think I am ok with the amendments but I struggled a lot with identifying the closest prior art. On one hand D2 deals with every leakage (including condensation), but D3 seems to solve the early detection problem but does not deal with condensation.

    ReplyDelete
    Replies
    1. I went with D3 because, like the invention, it relating to alerting to leakage. D2 did not provide any alert/alarm solutions.

      Delete
    2. Yes. The purpose of the present invention was fundamentally concerned with speed of detection. D2 taught a deep container - no mention of the speed urgency of early detection

      Delete
    3. I went with D2 for Claim 1 and D3 for the second Feature of Claim 6...

      Delete
    4. In the end I went for D3 as well, but took me a lot of time to conclude there and I am still not 100% confident.

      Delete
    5. Yes, D3 is CPA

      Delete
    6. Agree on D3 - the purpose of the invention was to allow detection of the leak which aligned with the purpose of D3. D1 and D2 had hints away from CPA in my opinion.

      Delete
    7. CPA was a bit challenging - I personally went with D2 over D3, but did make a lengthy statement at the end regarding how any document could have been started at and it would still be inventive. The recess and its purpose are inventive over any of the documents, so I will find it interesting to see how they mark the CPA section.

      Delete
    8. I also went with D2 for claim 1. Structural modifications required when starting from D3 seemed a lot more to me.

      Delete
    9. When I took Paper B, the intended solution had different CPAs for different claims. Likely the case here.

      Delete
    10. D2 and D3 were both solving very different technical problems. I went with D1 as it was at least solving the same issue as the characterizing part of claim 1 without going in a direction that would have actively taught away from the recess.

      Delete
    11. All drip trays deal with condensation; that is their raison d'etre

      Delete
    12. Purpose immediate detection of leakage yet allow normal condensation water to be retained

      Delete
  10. The description of the application definitely provided basis for generalising from V-shaped recess to just recess, but did it provide basis for separating the 10-20mm height from the recess?

    ReplyDelete
    Replies
    1. Yes. One of the paragraphs said any height could be used providing the front wall was lower. I think it was para 18.

      Delete
    2. Yes, in my opinion it did, because it was stated somewhere that they height is Not really important. And why would the recess only work with this height?

      Delete
    3. Right, V-shape best result but not essential

      Delete
    4. Yep. Only thing with the V-shape was to make sure that the embodiment with the skirting board was only dependent on the dependent claim with the V shape and not just 'any preceding' if you kept claim 5.

      Delete
  11. A nice paper this year, other than the exam report being a little terse.

    I think the solution was to incorporate the recess into claim 1 and claim 6, minus the V-shape. I also added that the recess did not extend all the way to the bottom of the front wall, based on FIG. 2 (using the rules for amendments from figures in the Guidelines). D3 CPA, D2 and D1 teach away. A recess may be implicitly disclosed in D1 due to the damaged front wall, but not in the embodiment with a lower front wall than side walls, and is disclosed as a negative thing, so D1 not a good starting point even if it arguable has more features in common.

    ReplyDelete
    Replies
    1. Interesting, you kept claim 6 as separate independent claim?

      I decided to not keep it independent and instead make it dependent on claim 5, because I thought the combination of recess and skirting board was only disclosed in the specific embodiment with the receivers / connection configuration as defined in claim 5.

      Delete
    2. Benchmarker in claim 6 i left the combination of skirting board + drip tray depdending on claim 1

      Delete
    3. Yes, I agree. As noticed above, it seemed a bit short, so I also wondered whether I overlooked something. I considered specifying that the recess had a height C lower than A but greater than zero, but in the end did not do that, mostly because I could not find a nice basis for that, nor any hint that something along those lines was expected. I did not think of using Fig. 2 as basis.

      And yes, D3 as closest prior art, so the invention solves longevity and false alarms.

      I made claim 6 dependent on claims 1-5 ('automatic' unity, and only one independent claim per category). I also made claim 7 dependent on the drip tray claims, as there was no connection to the skirting board.

      I made claim 5 dependent on claim 6 (and renumbered) to solve the lack of clarity, but the 'connectable to' mentioned above might have been better.

      Delete
    4. Why would a recess be inextricably linked to the receivers and skirting board?

      Delete
    5. I left it as an independent claim, mainly as claim 1 defined a drip tray, and claim 6 a drip tray and skirting board (i.e., claim 1 is an apparatus claim, claim 6 a system one). Ultimately, I think either way would be okay though, as long as you justify why.

      Delete
    6. Thanks for the above Benchmarker. Can you comment on how you think it will be marked if you chose D2 as the CPA? I know it taught away, but D3 had electronic detection means and arguably required more structural modifications than D2. I also noted that D3 would detect any level of liquid (due to the wires being on the base) so would alert the user to any level of liquid build up (including condensation forming a layer of water on the base) which is the opposite of what amended (to include the recess) claim 1 is trying to do.

      Delete
    7. Skirting board shoud have a height which allows to check the water leakage from the recess outlet I think. Otherwise is not enabling

      Delete
    8. @J, I am not a marker, so please take this with a pinch of salt, but there would typically be a lower, but non-zero number of marks available for inventive step arguments starting from the wrong CPA, as long at there are at least some reasonable reasons for starting there. For example, last year the maximum number of IS marks was 25 instead of 30 if you started from the wrong document.

      Delete
    9. Not agree, D3 is not the most easy springboard and it needs much more modification to reach the invention. The aim of invention is to detect leakae withoud electrical systems (description) so D3 bad starting.

      Delete
    10. The purpose of invention was to realiza a leakege detecting drip tray without battery or electric system which doesnt last fo years. D3 teches away. Not CPA

      Delete
    11. I think D3 taught away, since the application explicitly said in two different paragraphs that those alarm systems are too complex. Regarding the drip tray, D1 and D3 both dealt with the device damaging the structure, which made it unsuitable as CPA in my view.

      Delete
    12. D3 also detect any amount of leakage even condesation. False allarm. The invention let a small amount of water due to condensation without false alarm (no leakage). D3 teaches away

      Delete
    13. J is right in my opinion

      Delete
    14. @Steven and Anon. Well, we will see when the exam report comes out.

      My argument for D3 was that it was the only document relating to leak detection, which was the purpose/field of the invention (and in particular the recess feature). The fact that the application mentioned the type of drip trays used in D3 in a disparaging way shouldn't alter this - it would be a strange interpretation of the PS approach if prior art couldn't be CPA if its problems were discussed in the application.

      Also, the fact that a document teaches away from the solution doesn't mean that it can't be CPA - especially if the other documents also teach away in some manner. D2 emphasises sealing the drip tray and maximising water contained in it, which teaches away from the type of recess used in the application.

      Delete
    15. In my view, it is essential to define height C as being lower than height A. A front side that is lower than the other three sides inherently creates a recess at the front. If the recess is not defined by specifying a height lower than that of the front side, the claim may not be novel over D1, D2, and D3.

      Delete
    16. Interesting point with regard to defining the recess as being lower than the front and that D1-D3 all technically have recesses on their front walls. I didn’t think of that but did include the definition of C being lower than A in claim 1 as it made it easier to argue against the IS objection in the letter which outlined the recess as being non-inventive.

      Delete
    17. Agree with benchmarker re. D3 as CPA. Ultimately it is the purpose which defines the CPA, and the only prior art with the same purpose as the invention (which was in paragraph [7] from memory?), namely, to allow detection of the leak, is D3. The consideration of the number and nature of structural modifications is always a more ancillary consideration which almost always defers to purpose

      Delete
    18. Did anybody use G1/24 in view of arguing that D1 does not disclose a recess in the front wall?

      Delete
    19. I don't agree with D3 as CPA, D3 can't contain water just detect leakages with electric system. Invention is to detect leakages over an amount and let other free to dry without false alarm. Description of D3 also describes front wall must be 30 mm or less.

      Delete
    20. How did you manage to get G1/24 in?

      Delete
    21. I went with D1 as CPA as it was at least solving the same issue as the characterizing part of claim 1 without going in a direction that would have actively taught away from the recess.

      D2 and D3 were both solving different technical problems in different ways. Also means there's an interesting discussion of D1+D3 in the P-S step. D2 just felt like it was trying to achieve the exact opposite of what the applicant was.

      Delete
    22. D3: [005] A particular advantage of the drip tray is that even a small leakage can be detected
      immediately to prevent the floorboards from getting wet.

      Delete
    23. I went with D3 as the CPA also based on purpose , and described D3 as the most promising springboard because it is directed to a similar purpose. I also argued that to start from D1 or D2 would involve hindsight reasoning because D1 and D2 are not equally valid springboards (referring the problem solved not being recognised in D1 and D2). I then cited, inter alia, T 2759/17; Case Law (2025) I.D.3.2 and also chapter I.D.3.7.2, together with GL/G-VII, 5.1, as well as a relevant T decision citation relating to "equally valid springboards".

      Delete
    24. but detecting the water is the technical effect to me, the purpose of D3 and the otp is to prevent floorboard to getting wet.

      Delete
    25. Anonymous @2.41pm - why can't it contain water? From memory it said it could still hold water, just that it could detect with even very small amounts. There was also no height requirement on the front wall other than it being lower, so not sure how the 30mm height is relevant. D3 is the most promising springboard having the same purpose. Structural modifications are not as important as purpose for deciding CPA

      Delete
    26. The purpose of D3, or rather a particular effect deriving from the drip tray, is that "even a
      small leakage can be detected immediately to prevent the floorboards getting wet" (see [5]). This purpose is also described in para. [1] of D3 in that the drip tray is "for detecting a leakage underneath a kitchen appliance".

      The originally disclosed purpose of the present invention is to provide a drip tray which
      retains condensation and ensures that leakage is detected immediately. See para [7] of the
      present application.

      Delete
    27. I'm afraid I must agree with previous posters re. D3. In response to John, the purpose cannot be read so narrowly into one specific effect of D3. Much earlier in D3 (don't have the exact paragraph to hand...) it states that the aim is to allow detection of leaks which is the same as the claimed invention

      Delete
    28. @2:56 the aim was to detect leakage but not small amounts of liquid due to condensation. There's no reason D3 can't do this in theory, but there's also no reason to ever consider adding a recess when there's an optional switch to kill the water supply in D3. Personally I didn't see D3 as actually suffering from the problem of leakage.

      Delete
    29. In assessing CPA you should refer to MAIN purpose/problem/effect of claimed drip tray. How to detect leakages is not the main purpose to consider but how to prevent the floorboards from getting wet.

  12. Anyone left combitation ot dript tray according to claim 5, and skirting board? Claim 5 clarified by drip tray connectable o sutable to be connected?

    ReplyDelete
  13. Quite a straightforward paper thanfully, but requires lots of argumentation, intermediate generalisation, essentiality test, R43(2)(a), two times novelty and inventive step ...etc.
    I've added the feature of the height C being less than A from the description because D2 had an opening on a sidewall that can be interpreted as a recess.

    ReplyDelete
    Replies
    1. Furthermore, I had two independent claims: c1 covering a drip tray and c5 covering a skirting board connectable to said drip tray. The combination is therefore covered as per client request but i had to argue that the drip tray and skirting board are interrelated products.

      Delete
    2. All the same here, defending compliance with R43(2)(a)

      Delete
    3. But the client did not ask for protection of the skirting board alone? They only asked for (1) the drip tray and (2) the combination of drip tray and skirting board...

      Delete
    4. Agree with Marc, not quite sure why so many people tried to claim the skirting board alone?

      Delete
    5. the combination is covered by: "A skirting board connectable to the drip tray...".
      Alternatively, you can keep the term "combination" but it is less elegant in my opinion. In any case you still have to argue why the claim satisfies R.43(2)(a)

      Delete
    6. Agree with Marc. It's ugly, but that's Paper B.

      Delete
    7. Stefan - agree with the R43(2) requirement still being relevant, but what was raised was an Art 82 objection and the client asked for skirting board+tray and tray alone. Claiming the skirting board alone requires further limitations on the skirting board to meet both the requirements of Art 82 and R43(2) than claiming the system where you can have unity from same inventive concept being the recess in the tray, rather than having to find some unifying concept between the tray and board

      Delete
    8. I did not claim the skirting board alone!
      I just removed the term "combination" and replaced "connected" with "connectable the drip tray of claim 1".
      Art.82 and art84 objections stem from the same issue: the drip tray and the skirting board being two separate products. By amending the claims and proving that they are interrelated you solve the Art.82 and 84 issues at once.

      Delete
  14. I also added that the height C is smaller compared to A. It may be a limitation but I thought that it does not work otherwise. Did not think of the "not extending all the way" part but it makes sense.

    1. Isn't though implicit that when there is a recess on the front-wall where recess has height C and front-wall has height A, then C < A without needing to go further? My reasoning was this as I did not include the height. -FK

    2. I also added that heighy C is smaller han height A

    3. In my view, it is essential to define height C as being lower than height A. A front side that is lower than the other three sides inherently creates a recess at the front. If the recess is not defined by specifying a height lower than that of the front side, the claim may not be novel over D1, D2, and D3.

      Delete
    4. I don't think it's implicit. Recess cover A and C being identical and the recess simply being backwards in a different plane.

      Delete
    5. I agree that " front side that is lower than the other three sides inherently creates a recess at the front" But I think that's different from "frontwall (itself) comprising a recess", could not really understand how can A=C, when a particular wall has the recess. Because the wording was "front wall comprising a recess" which should prevent having a recess in a different plane.

      Delete
  15. Claim 5 was not clear "connected to" skirting board, needs "connectable" or suitable to be connected. Claim 6 combination od skirting board + drip tray according to claim 5. without snap clamping (not essential)

  16. Well that was a doddle lol. Why can’t the Exam Board make the difficulty consistent across the papers and year-to-year? Papers A and D were hard this year and B was relatively easy. I did Paper B from 2024 recently and found it to be an almost insurmountable task in the time given.

  17. The recess was the thing to add to claim 1 in my opinion, I kept that the front wall was lower than the other walls because that was in combination the solution to the problem of the homeowner not seing the water coming out, the recess made it more visible when there was a leakage, there was something about it in on paragraph, dont rememer the number but it was somewhere in the beginning.
    made dependent claims för heights, adhesive thing, and for receiving things adapted to be snappable connectable (not english speaking and not proud of it but couldnt word it any better) to legs of skirting board. I could not figure out how to claim the skirting board so I made no claim for it. Missed the prior art reasoning due to not having the time, but I finished novelty and basis for amendments. Could this be a pass or am i F-d? I have bonus point from previos years so 45 points would be enough. I really hoped I passed, I´ve been doing this each winter for ages now.

  18. The client was asking to protect the drip tray and the drip tray + skirting board, and not the skirting board independently. For that reason, I did not see the necessity of going down the road of two independent claims, two inventive step argumentation, and R.43(2).

    I also thought that such a skirting board would lack novelty over D3.

    I found it necessary though to further limit the system claim by incorporating the receivers, as that was an essential feature for mounting skirting board and the drip tray according to any one of claims 1-5.

    ReplyDelete
    Replies
    1. It took me long time understand if the client wanted to have an independent claim to the skirting board. In the end, I decided not to. I lost alot of time there though....I initially limited further with the receivers but then removed it. I think in the combination claim, I think 4 or 5 it says that the drip tray further has receivers?

      Delete
    2. I did the same and also limited the drip tray to the recess to establish unity.

      Delete
    3. Claim 6 didn’t have an independent skirting board, it had the combination of skirting board and drip tray, as in the embodiment of figure 3. Easy to unify them using the recess.

      Claim 5 needed to be amended to take out the skirting board, meaning claim 1 and 6 are now clear and unified and for different subject matter.

      I think it was equally valid to have claim 1 and 6 as two independent claims, or make 6 dependent on claim 1.

  19. Who else amended claim 1 to specify that the drip tray includes a recess forming an outlet based on the dependent claim? I did not specify the shape. As for the combination claims, I directed them to claim 1. So unity is achieved... Anyone else? I did not specify container size or so...

    2. In my view, it is essential to define height C as being lower than height A. A front side that is lower than the other three sides inherently creates a recess at the front. If the recess is not defined by specifying a height lower than that of the front side, the claim may not be novel over D1, D2, and D3.

  20. I struggled to understand whether the client was also asking for an independent claim directed to the skirting board. This was not clear from the English version. So I was constantly thinking about R. 43(2) as well. I limited the independent claim with recess and the receivers. Then, decided not to to have an independent claim to the skirting board and amended claim 1 with the recess (not of any shape)...

  21. Much nicer. I kept claim 1 and 6 as independent claims and added the recess to both. Argued that unified because both solving same technical problem and are alternate solutions/interrelated. Then used D3 as CPA for both claims 1 and 6.

  24. D3 detect any amount of water even condensation. Aim of invention is to detect leakages over an amount whitout false alarm and electric devices and let condensation dry whiotout alarm. How could consider D3 as CPA??

    Replies
    1. I spent around 15 mins to determine CPA, and went with D2 due to requiring much less structural modification. Fig.1 of D3 is misleading in itself since the walls and base comprise alarm system components like battery, wires etc, as far as I recall.

      Delete
    2. Purpose of the invention is to detect leaks... D1 and D2 do not do that, they only look to prevent overspill of the drip tray. D3 could therefore be considered CPA because it is also same purpose of detecting leaks. Not sure if this is correct, seems like you could argue from any of D1-D3!

      Delete
    3. I went with D1 for this reason. D2 and D3 are going off in wildly different directions to the point where you'd never even consider adding a recess and the "problem" is already solved in a different way. D1 doesn't, so it could be necessary to adapt it.

      Delete
    4. Agree, purpo immediate detection of leakage yet allow normal condensation water to be retained. Thus objective reliable leakage detecting drip tray.

      Delete
  25. I actually went for D1 as CPA, defining the OTP as reliably detecting leakages vs condensation (solved via recess). D2's tray is deeper and its front wall is only lowered for a hose, with no detection means. D3's front wall houses electronics (discouraging modification to the wall) and can't reliably distinguish condensation as its circuit is arranged on the base. D1, while hiding the drip tray in one embodiment, frames undetected leakages as a problem and shares most features in common.

    On reflection and seeing the comments here, I feel that my approach was a bit weaker than D3 as CPA. Interested to know if anyone took a similar approach or has any thoughts

    1. Right and front wall of D3 is descrived to be considerably shorter 30 mm or less! Cause it is not intended to contain water but just detect

    2. I actually used D1 as CPA for independent claim 1 based on collecting condensation (not possible with D3 without alert).
      And, I used D3 as CPA for independent claim 6 based on minimum modification (D1 and D2 require more modifications).

      Delete
    3. I done this and I stand by it. The problem is already solved differently in D3 to the point where you'd never even consider modifying it to include a recess. D2 just tanks it like a champ. D1 is the one where the problems / damage may still occur and require adaptation to overcome.

    Claim 6 and skirting board solve a different tech problem to make leakage visible whitour cover the front part of drip tray with recess. Alone is useless. Client letter says he wants to protect the drip tray and the combination with skirting board, not the skirting board alone.

    1. I can't remember the wording but it effectively defined the functional result of the recess. I'm pretty sure the wording had basis, just needed the structural feature of the recess to not be a result to be achieved. Mark schemes haven't penalised retaining functional language in addition to the structural feature responsible for the effect so long as there is basis

    2. changed it to a "such that" after the recess and height and rephrased it in terms of the description. Doesn't add much other than clarity but also isn't limiting.

  32. Is the addition of "that the front wall comprises a recess forming an outlet." (orig claim 3 without V-shape) not already establishing novelty over D2? The front wall in claim 1 is defined as being lower than the sidewalls. Therefore, excluding the embodiment in D2, where the holes are in the sidewalls that are higher than the lower sidewall...

    1. In my opinion, it does...

    2. You can argue it's implicit but "recess" is vague and covers a fictional embodiment where A and C are the same height and the recess goes "backwards" rather than "down" and doesn't solve the technical problem. It's probably nitpicking given how recess is defined in the paper, but I put it in anyway.

      Delete
    3. I kind of convinced myself that height is not needed. Recess can also be made in a way that it is only performed on a certain part of the wall with respect to its thickness. For example, inner portion of the wall has the recess with C<A but does not deliver the effect because remaining part is solid as rock. I do not think that height is essential, nor would I think that adding or not-adding the height will be penalized.

      Delete
    4. I don't think it does.
      In paragraph [004] of D2, the openings are provided in the sidewalls. This can be interpreted that all 4 walls are sidewalls, especially that paragraph [007] in D2 disloses a lower front side of the continuous wall.
      I might be wrong though...D2 doesn't have enough meat to draw a clear cut conclusion.

    1. D1. D3 won't leak.

    2. D3 since the purpose is immediate detection of leakage yet allow normal condensation water to be retained

      Delete
    3. I ended up with D1.

      D3 already solves leak detection by an electrical alarm/switch, so starting from D3 makes it harder to explain why the skilled person would look consider looking for a different, passive overflow-based detection mechanism in D1 or D2.

      By contrast, D1 is already a passive drip tray with the same basic lower-front-wall geometry, so it is the cleaner CPA if claim 1 is about tray structure rather than electronics when you take into account that it's an exam and you have to write CPA + prior art inventive step arguments. If you start from D1 then D2 and D3 teach away.

      If you start from D3 then D1 and D2 are just less functional and useless.

      Backwards engineering it somewhat, but I think both are fine depending on if you see the recess as a "system for leak detection" or "technical feature of drip tray geometry".

      Delete
    4. I opted for D1 fot the following reasons: Field of invention same of D1 D2 D3 (drip trays), main purpose/problem same of D1, D2, D3 (drip trays prevent the floorboards from getting wet); few structural changes: modyfing D1 just need adding a outlet recess on front wall. Modifying D2 needs adding outlet recess on front wall and eliminating opening 5. Modifing D3, needs adding a outlet recess and eliminate alarm, battery and wires.

      Delete
    5. D2, because it stated the problem of rising costs to insurance companies...

      But I honestly think that D3 should have been CPA due to electronic detection being described as problematic...

    1. I specified the height like you, just to be safe. Even if it was not necessary, it does not limit the scope of protection in any way. As for the receivers, I don't think those were essential.

    2. So I added the height bit too as I thought it helped with distinguishing it from D2 which had the holes but these holes were above the front wall (otherwise water would just flow out). Am now worried about added matter, but hopefully fine as same feature described in Fig 1 as well as Fig 3.

      Amended to polypropylene + preferred anti-funghi compound. I considered that this specific combination is disclosed since they are both referred to as being part of the preferred embodiment. The client wanted us to protect PP or PE + the prefereed anti-funghi compound, but PE is not disclosed in combination with that specific anti-funghi compound. Any other specific combination would not be OK for 123(2).

      I'd have to check the wording of the paper again to be sure I didn't make a mistake though

    1. You can achieve the same technical effect of the recess by simply inserting a recess into D3. You don't have to remove the alarm system from D3 to achieve this technical effect. It's compatible with the circuit and alarm and battery of D3, it's just that the alarm system becomes redundant. As such u don't need to remove the alarm system.
      CPA is always the document directed toward the same field, here the detection of a leak. D1 AND D2 make no attempt to detect a leak

    2. A 3:54 Field of invention is Drip trays for kitche appliances. Detection of leak is an effect purpose to me but not the main purpose effect whic is to prevent floor to getting wet.
      Making a recess on D3 does not allow you to reach the claiming solution because you always have fals alarm even for condensation which does not allow you to let condensation dry and leakage outlet on front of tray.

    1. Isn't sealing them up removal of feature? My thinking was D2 needed more modification than D1. D2 needed sealing of holes and sealing means need to be procured, in addition to creating the recess. D1 only needed creation of recess.

    2. So anything on which you can make a recess outlett is suitable. That's not the criteria. Standing the same technical fiels and the same main purpose, the minumun amount of changes are obtained just selecting D1. If there is mush more to consider is another thing.

    3. If your drip tray give you an alarm before lever of water reach the recess, you can wait the tray to fill and water being direct on the floor by outlet recess to detect it.

On the other hand, I correctly referred to "clarity" at the end of the section, saying that the obejction of lack of clarity has been resolved.

  42. I envisage quite a high pass mark for this as I think, while D3 was CPA, D1 and D2 both provide good starting points for a convincing inventive step attack. At the end of the day, the aim of the paper is to assess one’s ability to convincingly argue and get a broad set of claims granted for your client, and if that can be done starting at any prior art document then you should be rewarded. None of the documents hinted at a recess so no possible combination of documents (irrespective of where you start) would result in the amended claim 1. I think the examiners might regret setting an exam where one could argue convincingly from any of the prior art documents.

  43. What do you think about an amendment of claim 5 specifying that the drip tray "comprises" a skirting board? Not sure why I put it this way but I tried argumenting that by connecting the skirting board to the one could say that it is "comprised", which admittedly does not sound particularly convincing in hindsight. Still I think it overcomes the problem of reference to another entity.
