|What Kats do on|
* "£700 demand letters: no Golden Egg for Golden Eye", here. The IPKat admires a masterly summary by Mr Justice Arnold of the law relating to how not to chase allegedly copyright-infringing file-sharers.
* "KAT UPDATE: latest decision in Tulisa sex tape case", here. Cat the Kat continues the sad tale of attempts to suppress the most-watched movie since Avatar ...
* "Don't say "no" to cross-border patent relief, says AG, say "nuance"", here. The Kat reviews the Opinion of the Advocate General in Case C 616/10 Solvay SA v Honeywell Fluorine Products Europe BV, Honeywell Belgium NV and Honeywell Europe NV.
* "IBIL seminar report: where are the leaders in copyright law?", here and here. If you missed every one of William Patry's speaking engagements in London earlier this month, read these posts and you'll feel so much there that you'll even be able to taste the canapes. Double whopper from Annsley the AmeriKat.
* "Battle of the Tablets hits the UK - Samsung seeks declaration of non-infringement of Apple Registered Community Design", here. Guest Kat Darren explains that this battle of the Titans is just the hors-d'oeuvres.
* "Unfair dinkum in film copyright case", here. Cat the Kat goes Down Under in order to bring a warning that it can be dangerous to threaten to sue folk in Australia for copyright infringement if you don't have a solid ground on which to make that threat.
* "Bunnies - Austrian Supreme Court delivers Easter egg to Lindt & Sprüngli", here. With season precision, Birgit delivers a chocolate bunny ruling all the way from Austria and peels the wrapping off a fascinating Supreme Court decision.
* "So Who Gives Copyright Advice to the Copyright Lawyer?", here. Never one to worry about trivia, Neil shares his latest anxiety with the Kats' sympathetic readership.
* "Happy Easter from the AmeriKat I: Appeals Court rules in Viacom v YouTube", here. No need to guess the author here -- or the subject-matter.
* "Happy Easter from the AmeriKat II: Gucci v Guess, USPTO and ITC news", here. Another masterly round-up of those transatlantic tribulations from our very own specialist.
* "Breaking News: 4th Circuit paves a partial path for Rosetta Stone in Google Adwords case", here. A helpful analysis of a ruling which is not the end of the story but perhaps the beginning of the end -- a ruling which has also been much misunderstood in the non-specialist media.
* "Sanofi Aventis Taxotere Patents invalidated by CAFC", here. To the untutored reader, "Sanofi Aventis Taxotere" might sound like one of the magic spells from Bedknobs and Broomsticks, but discerning guest Kat Darren picks up its deeper meaning.
* "Mama Kat Blues: protecting our babies' names", here. Waking from her hibernation, guest Kat Tara introduces non-US readers to the unfamiliar terms "blue ivy" and "travyon" which, on closer inspection, turn out to be forenames.
* "Complicated, replicated! Will me-too site be a match for Match.com?", here. Miserably failing to escape from her stereotype of the Kat team member who blogs on all the smutty stuff, Cat the Kat finds herself at the keyboard again, typing things which polite Kats would never even think of ...
* "Patents and Jurisdiction I: Solving Solvay", here. Instantly seeing through the IPKat's attempt here to bluff readers into thinking he knows anything at all about jurisdictional issues, none other than the celebrated Willem Hoyng steps up to give readers a lesson on the subject.
* "Patents and jurisdiction 2: Innovia v Frito-Lay", here. Now that he has suddenly become an expert on jurisdictional matters, the IPKat explains another ruling by Mr Justice Arnold, this time in Innovia v Frito-Lay.
* "AOL and Microsoft: Patent Strategy Ain't What It Used To Be", here. A controversial post by Neil on the mass acquisition of patents and the role of the patent portfolio once it leaves the hands of its original owner.
* "Boundless flattery of leading textbooks", here. Here, at his thoughtful best, guest Kat David accounts for an interesting business model for US textbooks which is apparently based on copyright infringement.
* "Two groups, one name, no joy, as bands and lawyers head in One Direction", here. At last, Cat the Kat escapes from all that smutty stuff and describes a squabble between two identically named bands in which there's no mention of anything more sordid than Vegemite.
* "Lost in IP Translator -- a trilogy of treatises: I", here. In the first of three most thoughtful posts, veteran IP practitioner and katfriend Richard Ashmead explains how the expected Court of Justice ruling in IP TRANSLATOR might have an impact on marks that have already been registered within the territory of the European Union.
* "Swing the axe, glue the tail, spin the coin: damages for patent infringement", here. Great celebrations here, as Matt the Kat -- currently taking a break from the blogosphere -- makes a welcome return with this analysis of a long-drawn-out battle in which our very own Annsley starred.
