1. An Official letter dated 18 September 2015 explained that the invention of claims of the above patent was not new or did not involve an inventive step and that revocation of the UK Patent under Section 73(1A) might therefore be necessary.
2. The proprietor contested this view in their letter dated 29 September 2015. I have considered their observations and I make no order for revocation of the UK patent.As I reported briefly in the update to my previous post here, the patentee had argued that the examiner got it wrong by interpreting the claims incorrectly, and made no amendments to the patent. They could, of course, have done this instead by requesting a review of the opinion and should have got the opinion set aside. We would, however, then have had a decision of why the opinion was wrong. The decision here goes into no detail at all about why the opinion was wrong to decide that the patent was invalid, which it presumably must have been if the patent is not being revoked. I wonder therefore whether the IPO is taking this thing entirely seriously.
