T 2395/19 - Review of facts, public prior use

Key points

  • An example of the new style review of findings of facts, by Board 3.2.01.
  • "The Board confirms the conclusion of the opposition division that the appellant (opponent) has convincingly and sufficiently proven that a public prior use of a coated cutting tool type "Tiger-Tec WAK1O" manufactured by Walter AG took place before the priority date of the contested patent (December 2004). 
  • "To the extent that there is no error in the application of law, in principle a Board has no reason to set aside the evaluation of evidence of a deciding body of the first instance and supersede it by its own unless the deciding body of first instance recognizably failed to consider essential aspects, included irrelevant considerations, or violated the rules of logic, such as when logical errors and contradictions are detected by the Board in the reasoning of the decision (see also T1418/17, point 1.3 of the Reasons, T 42/19, point 3.4 of the Reasons)."
  • " The burden is on the party challenging a fact on appeal to demonstrate that the first-instance department erred in its finding of fact. In doing so, the party must specifically point to each alleged error in the department's findings of fact or in its evaluation of the evidence and set out the reasons why this is considered erroneous (T 1138/20, point 1.2.5 of the Reasons)."
  • On the standard of proof: "The Board also considers that it has been proved beyond any reasonable doubt (see affidavits D26, D26a and D49) that coated cutting tools of type "Tiger tec" with grades WAKl0 manufactured by Walter AG were available on the market as a "mass product" to everyone - hence also to the appellant (patent proprietor) - at least from July 2004, i.e. before the priority date of the contested patent (December 2004)."
  • The fact that the specific test specimen was tested in house, does not raise the standard of proof to "up to the hilt".
  • "It appears to be normal that a party submits their own experimental data be it produced within their company or an affiliate company. This may lead to a need of the other party to run comparative tests and submit the results if they shed doubt on the other party's data. But it does not lead to a shift of the standard of proof since both parties are free to run their own tests on standard products available on the market. Should the other party contest the comparative results based on the fact that material properties may change within a series of products they would be under an obligation to provide a specimen out of the toolbox acquired by them for further inspection by the other party or by an expert appointed by the opposition division. "
    • This is the EPO-appointed expert of Art. 117(1)(e) EPC. Does anyone know of a case (appeal or application number) where one was appointed? (asking for study and teaching purposes)
  • "The credibility of the declaration signed by the employees of TaeguTec was questioned by the appellant (patent proprietor) ..."
    • As a comment, if signed declarations are timely (contested before the OD (in a substantiated way), the declarant should normally be offered as a witness by the party filing the declarations. The decision indicates that the opponent did offer witnesses. 
    • "As a consequence of these findings, the taking of evidence in the form of a hearing of the witnesses Mr. Na and Mr. Lee offered by the appellant (opponent) was not required." (by the OD)
    • E-IV, 1.2: "If the alleged facts are contested by the other party, the opposition division does not generally base its decision on such a statement, but summons the person making the statement as a witness, if so offered by the party. The ensuing hearing of the witness allows the opposition division and the parties to put questions to the witness and thus enables the opposition division to establish the facts on the basis of that person's testimony." (see also T0474/04)

  • "The complaint of the appellant (patent proprietor) that they were not able to carry out counter-tests of the same specimens tested by Mr. Lee and Mr. Na is not justified either because, as confirmed by the appellant (opponent), no request in this sense was submitted by the appellant (patent proprietor) to the appellant (opponent) and the contrary has not been proven by the appellant (patent proprietor). The Board also observes that the appellant (patent proprietor) did not make any attempt to purchase and counter-test specimens of "Tiger-tec WAK1O" coated cutting tools which were available on the market at least as from the year 2024 in order to confute the results presented in the affidavits under discussion."
  • The Board considers and rejects numerous other objections to the evidence by the proprietor.
  • "The subject-matter of claim 1 according to the main and to the auxiliary request 1 thus lacks novelty over the public prior use, whereby irrespective of the further issues raised by the appellant (opponent) these requests are not allowable as correctly stated by the opposition division."
  • The patent is maintained in amended form: "The Board agrees with the appellant (opponent) that the solution recited in claim 1 defines an alternative to the known "Tiger-tec WAK1O" coated cutting tool because the advantageous technical effect claimed by the appellant (patent proprietor) is neither mentioned in the contested patent nor was this technical effect demonstrated by the appellant (patent proprietor). However, the Board considers that the elevate number of parameters at stake and the complexity of their interactions which, as it is well known, characterizes this kind of composite products, suggests to the person skilled in the art to apply extreme caution when considering to replace a component of a very well working composite material as the coatings of the "Tiger-tec WAK1O" cutting tool with a different one. Therefore, the Board agrees with the appellant (patent proprietor) that the person skilled in the art has no motivation to replace the material of the third coating of the public prior use cutting tool with the materials suggested in claim 1, whereby the subject-matter of claim 1 results in an non-obvious alternative to the solution known from the prior art."
