T 0953/23 - The proprietor's own prior use

Key points

• The inventor is "PREISSMAN, Howard".  The OD rejected the opposition. The opponent appeals. The proprietor is Keller Medical, Inc.
• "D1 is an article published in 2012, i.e. after the filing date of 29 April 2009 of the patent [filed without priority]. The article concerns the development of the "Keller Funnel". 
• "In the section of D1 entitled "Serendipity", second paragraph, it is explained that Mr Preissman perfected the funnel's design  ..."
• "On the first page of the article (p. 283 at the bottom right), it is stated that "[w]e began introducing the prototype and its potential benefits to influential plastic surgeons at the beginning of 2009 ...". The appellant [opponent] alleged that it followed from this passage that the invention had been disclosed to the public, namely to influential plastic surgeons, before the filing date of the patent in suit."
• The Board: "In the absence of any indication of a different understanding, the Board interprets the expression "at the beginning of 2009" in accordance with general linguistic usage. According to which "at the beginning of 2009" refers to a point of time not later than within the first three months of 2009. Had a later period been intended, wording such as mid 2009 would have been used. Thus, the Board is convinced that, on the balance of probabilities, the disclosure to the influential plastic surgeons did take place before the filing date of the patent in suit."
• The Board, earlier in the decision: "it is common ground that the facts relating to the prior use were not under the control of the appellant and that both parties had equal access to the evidence. In accordance with the principle of free evaluation of evidence and in line with the established case law (see CLBA 11th edition, III.G.4.3.2 a)), the Board assessed the relevant facts on the basis of the balance of probabilities."
• I'm not sure if the part in italics is entirely accurate, but for the outcome of the case, this detail does not matter.
• The patent is revoked.
