Can anybody confirm that Sigma-Aldrich has nothing in this family that is pending (or issued) in any other Patent Office. I thought it might be interesting to see what has happened at the EPO, but I drew a blank.

May I ask: did Sigma file outside the USA; at the EPO, for example. I thought it would be interesting to see what issued there, and whether any opposition to it was filed.

I had a look but found nothing. Any idea, anybody?

Seek and ye shall find. Thanks Max

Under opposition proceedings 3/2020

Kevin, thanks. As you say.

I see now that at the EPO the one family member to get to grant has attracted oppositions from ten parties, eight of which are various patent attorney firms on behalf of their unidentified client.

Here is a Link to the 30 page Oct 22, 2019 Summons to oral proceedings. At first glance, it doesn't look too bad for the patent owner. Priority back to the US filings, novelty, inventive step, enablement. As usual though, it's the amendments after filing that are giving the patent owner a belated head-ache, after the EPO issued the patent. That's the thing, isn't it, with FtF. You have to be early to file but not so early that you fail to include an enabling written description of exactly the invention you are paying so much to protect. Otherwise, you end up with nothing while readers have been creaming off everything you wrote that is useful to them, ever since the day of publication of your WO-A disclosure.
