Key points
- This is an appeal against a decision of an Examining Division refusing the application and refusing the refund of an additionally paid search fee under Rule 64.
- "The examining division refused the application on the basis that the main request and auxiliary requests 1 and 2 did not meet the requirement of an inventive step, Article 56 EPC, and because auxiliary request 3 was not admitted under Rule 137(3) EPC. It rejected the request to refund a further search fee because it confirmed the search division's non-unity objection against the original set of claims."
- An amended set of claims was filed in appeal after the Board cited new prior art of own motion and in reply to clarity objections of the Board. The Board considers those claims to be allowable.
- The invention is interesting but too advanced software technology for me.
- D1 was the master thesis of one of the inventors on the same topic.
- "The first two authors of D8 are the inventors of the present application. D8 is reference [137] in the later-published PhD thesis of the second author, to which the appellant drew the attention of the board in the grounds of appeal (page 26, fifth complete paragraph)."
- "The board noted that it was not convinced by the examining division's inventive step lines of argument starting from either D1 or D2. However, claim 1 of the main request and auxiliary requests 1 and 2 did not appear to involve an inventive step starting from D2 combined with common general knowledge as illustrated by D8."
- Turning to the requested refund of the additionally paid search fee: "As the appellant's refund request concerned only the further search fee paid for original claims 10 and 11, the examining division had to assess whether the communication under Rule 64(1) EPC was "justified" - within the meaning of Rule 64(2) EPC - to the extent that it required a further search fee to be paid for original claims 10 and 11."
- "In a number of board of appeal decisions, it has been considered that the scope of the review under Rule 64(2) EPC (previously Rule 46(1) EPC 1973) to be carried out by the examining division is limited to the consideration of certain facts and/or arguments."
- " it was considered in T 188/00 that "a review of the finding of lack of unity of invention has to be carried out having regard only to the facts presented by the search division in its communication under Rule 46(1) EPC [1973]" and that "the examining division has to base its review solely on the documents cited in the partial search report and on the specification of the different inventions drawn up by the search division, while taking into account arguments which the applicant may have submitted in support of his request for a refund"
- "The limitation to the facts presented by the search division, in particular the cited documents, postulated in T 188/00, has been followed, for instance, in T 1476/09, reasons 3, T 2285/17, reasons 4.2, and T 2873/19, reasons 9.1. In T 188/00 and in T 1476/09, the board found that the examining division's reasoning why the communication under Rule 64(1) EPC had been justified was incorrect because it relied on prior art that had not been cited in the partial search report (see T 188/00, reasons 4.6, and T 1476/09, reasons 3)."
- "The present board agrees with T 188/00 to the extent that the examining division may only find that the communication pursuant to Rule 64(1) EPC was justified within the meaning of Rule 64(2) EPC on the basis of the facts regarding the prior art presented by the search division with that communication, in particular the documents cited in the partial search report including sheet B.
On the other hand, the present board considers that a finding that the communication was not justified may well be based on further facts (for instance in the circumstances of the case in T 755/14)."
"the present board considers that, in the context of Rule 64(2) EPC, the examining division may, in order to find the communication under Rule 64(1) EPC to have been justified, complete a reasoning outlined by the search division with the communication but may not replace it by an entirely different reasoning, even if based on the same prior art."
"This position takes account of the fact that the applicant has to decide whether or not to pay further search fees only on the basis of the information provided with the communication under Rule 64(1) EPC. Where the search division decides to provide arguments with the communication as to why a further search fee would have to be paid, this is to enable the applicant to understand at this stage why the invitation is justified. The applicant would inevitably rely on these arguments to assess whether it is actually entitled to a complete search for a single search fee and, if so, would pay the further search fee with the expectation that it will be refunded upon review. In the board's view, it would be undesirable as a matter of fairness that such a refund may later be refused by the examining division because the communication is considered to have been "justified" based on an entirely different reasoning than that contained in the communication."
"When assessing whether the application documents on file comply with the requirement of Article 82 EPC, as a requirement for the grant of a patent, the examining division is not bound by the search division's opinion on unity of invention "
"for the reasons given at points 16.3 and 18.1 above, the board is not convinced by the reasons given by the examining division on why claim 1 of the then main request lacked an inventive step over D1 or D2 combined with D7. It follows that the board is also not convinced by the reasons given by the examining division in the context of Rule 64(2) EPC (and a fortiori by the search division) on why original claim 1 lacked an inventive step."
"The additional search fee was paid for claim 10. ": The reasoning of the examining division, like that of the search division, ignores at this stage the dependencies of these claims [i.e. claim 10] (apart from their dependency on claim 1) and appears to have only considered the additional features defined in each of the claims."
"Original claim 10 was directed to a "method according to one of the preceding claims 3 to 9" and original claim 11 to a "method according to one of the preceding claims 3 to 10". Hence, at least the subject-matter of original claim 3 (itself being dependent on original claim 1) was common to the first and the second "search subjects". They may only be non-unitary if original claim 3 was not inventive, but this has neither been alleged nor established by the examining division in its reasoning on Rule 64(2) EPC.
" The board therefore concludes that the communication pursuant to Rule 64(1) EPC was not justified and the further search fee paid for original claims 10 and 11 is thus to be refunded, Rule 64(2) EPC."
The decision also contains interesting remarks on Art.82.
