2016 FC 883 - The Federal Court followed the longstanding rule against the use of patent prosecution file history in interpreting the claims of a patent, but made a strong case for why the patent prosecution file history is worth considering, as is common practice in the U.S.
In U.S. patent infringement, the “actual notice” requirement in 35 USC § 154(d) requires actual knowledge of a published patent application. Knowledge of related patents, even those sharing a description, and indirect references to a published patent application in emails may not be sufficient to prove actual notice.
Les Laboratoires Servier v Apotex Inc,  UKSC 55 - The UK Supreme Court rejected the argument that patent infringement could form the basis for the defence of illegality since patent rights do not give rise to the sort of public interest consideration that underpins the defence of illegality.
Mediatube Corp. and Northvu Inc v Bell Canada et al, 2014 FC 237 - The Court dismissed a motion to remove Bereskin & Parr as solicitors of record for Mediatube for a conflict of interest, finding that “[w]hile there may be some circumstances where related companies could be considered as one entity and one client, the circumstances in the present case do not lead to that conclusion.”
