Dave,
I have tried US14675202, this search also does not yield any patents either.

There are 9 US patents with EVPN in their title and Juniper as their assignee in the USPTO database, but none of them seem to apply.

Regards,
Sasha

As amusing as it is to confer the forwarding of inter-subnet multicast with the processing of egg yolks,
I suspect the disclosure should have referred to US14675202 and not US4675202

Subject: Re: [bess] IPR Disclosure Juniper's Statement about IPR related to draft-ietf-bess-evpn-irb-mcast


Hi all,

I have looked up the IPR Disclosure Statement (pure curiosity) and it looks a bit strange to me.

In particular, a search for the US Patent  4675202 yields a patent for egg yolk processing<https://patents.google.com/patent/US4675202> that is owned by NESTEC (with priority from 1984).



At the same time, a search<http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=0&f=S&l=50&TERM1=EVPN+INTER-SUBNET+MULTICAST+FORWARDING&FIELD1=&co1=AND&TERM2=&FIELD2=&d=PTXT> for “EVPN INTER-SUBNET MULTICAST FORWARDING” in the US Patent Office database did not yield any results at all.



My 2c,

Sasha
