Court: Delaware District Court
Judge: Gregory M. Sleet
Case Summary:
Virginia-based company Relay IP
filed an IP case against BT Group PLC accusing the UK-based company of offering
routers, Ethernet switches, services and other products that infringe a patent.
The patent involved in the suit was US5331637 entitled ‘Multicast routing using
core based trees’ issued on Sep 19, 1994 and expired[i]
on Jul 30, 2013. The patent relates to transmitting information organized into
packets between nodes of a communications network.
The patent was last assigned[ii]
to Mosaid Technologies (source: MaxVal’s Assignment
Database.) According to the complaint, Relay IP is the sole and exclusive
owner of the ’637 patent.
Defendants infringed by using the
method claimed in distributing data and/or data feeds via distribution
networks, including BT Radianz Services, which practice the Protocol
Independent Multicast-Sparse Mode standard (PIM-SM) for multicast routing.
Defendants’ act of practicing the PIM-SM standard constitutes infringement for
which they are directly liable, said the complaint. Relay IP sought adequate
compensation of no less than a reasonable royalty.
The parties settled the dispute among
themselves and thereafter, joint motion to dismiss the case was filed by Relay
IP. The joint motion requested relief of claims and counterclaims asserted in
this case. Court granted the motion, ordering dismissal of claims with
prejudice and counterclaims without prejudice, with all attorneys’ fees, costs
of court and expenses incurred by the same party.
Relay IP has filed nearly 25
lawsuits alleging infringement of the same patent.
