To follow up from my previous posts (here, here and here) on the subject of revocation following request for an opinion on validity, this is to provide a little update on where things currently stand. At the time of writing revocation proceedings have been initiated in three cases. These are:
GB2497956 (JCB): Proceedings were initiated on 7 August 2015, with an initial deadline of 7 October to file observations and/or amendments. This has now been extended to 9 December 2015.
EP1837182 (Fujifilm): Proceedings were initiated on 16 September 2015, providing a deadline of 16 November 2015 (extendable by two months).
GB2487996 (Jemella): Proceedings were initiated on 18 September 2015, providing a deadline of 18 November 2015 (extendable by two months).
Two further opinions, 07/15 and 10/15, look likely to result in initiation of revocation proceedings. The proprietors have until 11 November and 24 November respectively to request a review of the opinion under section 74B.
UPDATE 4 November 2015: It seems that Jemella are keen to defend their patent. Their attorneys have responded with a letter arguing essentially that the examiner got it wrong by interpreting the patent incorrectly, and are not offering any amendments. I'm not sure why they didn't do this previously by requesting a review of the opinion.
