IMHO these were the top 10 news developments for IP practitioners in 2010:
10 Unilever Plc and others v Shanks
 EWCA Civ 1283
Clarified the law relating to employees’ patents. See my case note of 27 Nov 2010.
Last published draft of a proposed international agreement to co-ordinate anti-counterfeiting enforcement.
8. Twentieth Century Fox Film Corporation and others v Newzbin Ltd
 EWHC 608 (Ch),  ECC 13,  FSR 21,  EMLR 17,  ECDR 8
I took over the defence of Newzbin Ltd. but that’s not the only reason why I think it is important. This was the first fully argued English decision on the meaning of “communication to the public”. It also rowed back from the Amstrad cases on authorization.
Business method inventions are patentable in Canada. First Commonwealth decision to that effect – but see
US law on software-implemented and business method inventions inches closer to Europe.
Dog’s breakfast of a statute passed in dying days of New Labour imposing enforcement duties on ISPs.
Umpteenth review of UK intellectual property laws.
3. Google France and Others v Louis Vuitton and Others
 EUECJ C-236/08,  RPC 19,  ETMR 30
Search engine’s liability for use of keywords and ad-words.
The legal mechanism by which we may – just may – get the next best thing to an EU patent.
The most important IP development of the year: making the courts affordable to SME.
Happy New Year!
