The IPKat and his friends: a round-up of some IP weblog news

New and recent readers of this weblog may not know it yet, but every three months or thereabouts, the IPKat and Merpel give an update of the goings-on both on this weblog and on other IP-flavoured blogs to which members of this blog team contribute. Back in January we were able to introduce readers to our three current guest Kats (Tom, Valentina and Suleman), who are now just over half way through their six-month term of office.  This time round we are happy to welcome readers back from their Easter/ Passover break and to start with some news about the IPKat.


Over the past few weeks, the stream of visitors to this weblog has continued to grow. Since June 2003 we've now received more than thirteen and a quarter million page views. Nearly 9,300 individual blogposts are online and can be searched via the blog's search box at the top left hand corner of its home page.  This year looks like being our busiest ever. So far, over half a million visits have been made to us, around twice the volume of readers at this time last year.

The number of readers receiving Katposts by email is, at the time of writing, 11,492, and this blog is pursued by over 10,600 followers on Twitter at @Ipkat. The most frequently-visited blogpost remains Catherine Lee's June 2011 item, "Goodbye Cathy: Hello Kitty and Miffy settle copycat case", here, which has been visited more than 239,000 times. The blog operates a moderated comments facility and invites readers to post comments that are relevant, responsible and neither obscene nor insulting.  At present the number of readers' comments posted to this weblog stands at 24,531 -- and we give a big "thank you" to those who have taken the time and trouble to share their thoughts and information with us and with our readers.


The Kat's blog friends. Every few months this weblog lists, in no particular order, a number of IP -flavoured weblogs with which members of the IPKat's blogging team are associated. If you've not yet come across them -- and many of our more recent readers probably have not -- we hope that you will find some merit in them. For the avoidance of doubt, this list only relates to IP blogs to which Kat team members contribute: it is not intended as an exhaustive list of intellectual property blogs, or of blogs that have received our personal blessing. That's why there are plenty of IP blogs that are not listed, even though we know about them, like them and often read them!

Class 46, founded by friends of European trade mark organisation MARQUES and driven by a big team of international contributors, delivers trade mark and brand-related news and developments from across Europe ( As of today, this blog has no fewer than 4,314 email subscribers and a searchable database of nearly 4,000 items -- mainly relating to European case law and office practice but with coverage of plenty of other themes too, including plain packaging of tobacco products and the latest WIPO and OHIM initiatives for assisting users of the international and Community trade mark systems. Kats Jeremy and Birgit both contribute to this blog, as do former guest Kat Laetitia Lagarde and emeritus Kat Mark Schweizer.  
Class 99, founded by patent and trade mark attorney David Musker, is dedicated to design law and practice in the UK, in Europe and beyond ( This weblog is now part of the MARQUES social media family along with Class 46. It has 1,572 email subscribers and a searchable database of over 620 items.  New blog team contributors are earnestly sought from among the ranks of those who are either MARQUES members or work for a company or firm that belongs to MARQUES.
Incidentally, Class 46 and Class 99 are just one small but significant part of MARQUES's social media presence. Posts on both blogs are usually recorded on MARQUES's Twitter account at and all sorts of items concerning trade marks, brands and designs are likely to end up on MARQUES's Facebook page, which you can access at MARQUES also has a very busy and carefully moderated LinkedIn discussion group, with well over 3,300 members.

The 1709 Blog, which caters for the copyright enthusiast and seeks to cover all aspects of copyright law and practice in all its rich and varied glory ( As of today, this blog has 2,392 email subscribers and a searchable database of over 2,000 items. It has a large and international team of contributors: Glastonbury Festival's Ben Challis, IPKat bloggers Eleonora and Jeremy and recent guest Kats Alberto Bellan and Marie-Andrée Weiss, Professor Mira T. Sundara Rajan, John Enser (Olswang), Iona Silverman (Baker & McKenzie) and our man in Paris, Asim Singh. You can follow this blog on Twitter, here.
The SPC Blog is a handy information source for anyone who is involved in the tiny but controversial and highly lucrative world of supplementary protection certificates (SPCs) for pharmaceutical and plant protection patents, as well as other forms of patent term extension ( As of today, this blog has 2,037  email subscribers, many of whom have enriched the content of this weblog with their comments and through the provision of information concerning SPCs. This blog contains nearly 600 items, including English translations of some European national decisions that are not available elsewhere.  Incidentally, The SPC Blog organises an annual seminar, which is free to all comers and provides a great opportunity for pharma patent-owning companies, generics, private practitioners and patent office functionaries to get together and compare notes.
PatLit tackles patent dispute resolution topics -- principally litigation -- not just from the UK but from wherever interesting news and comments emerge. As of today this blog, whose contributors include Michael Thesen, former guest Kat Stefano Barazza and David Berry, has 1,459 email subscribers and a searchable database of getting on for 950 items.
IP Finance, which was launched in January 2008 in response to the UNCITRAL initiative on security interests in intangibles, touches that delicate interface between intellectual property and the world of finance, addressing securitisation, valuation, royalty rates, assessment of damages and the evolution of new business plans ( As of today, this blog has 1,537 email subscribers and a searchable database of 1,262 items. Kats Neil and Jeremy write for this blog, which is also garnished with content from academics Mike Mireles and (F)RAND expert Keith Mallinson (WiseHarbor).
jiplp is the blog of the leading Oxford University Press monthly publication, The Journal of Intellectual Property Law and Practice (JIPLP), which IPKat team member Jeremy (, with assistance from Deputy Editor Eleonora. As of today, this blog has 977 email subscribers and a searchable database of 578 items. This blog's content includes Current Intelligence notes, book reviews, requests for articles on specific topics and occasional guidance as to how to write (or not to write) good IP articles. There's an active and carefully moderated LinkedIn Group for JIPLP contributors and readers with over 330 members, which you can see here.  You can also follow this blog on Twitter here.
Afro-IP (, for which the blogmeister is Darren Olivier, deals with the IP scene in Africa. As of today, this blog has 877 email subscribers and a searchable database of nearly 1,800 items. This blog, which offers the largest single searchable online source of recent African IP news, features Caroline Ncube, Jeremy Speres, Isaac Rutenberg and Chijioke Ifeoma Okorie within its blog-squad.  Afro-IP can be followed on Twitter here.
IP Tango (, which is a bilingual blog with contributions both in Spanish and English, covers the increasingly important developments for IP in Latin America. As of today, this blog has 531 email subscribers and a searchable database of over 1,400 items. Like Afro-IP, IP Tango is a major source of intellectual property information and comment in its increasingly important area of focus.
Art & Artifice ( As of today, this international weblog, which includes Simone BlakeneyRosie BurbidgeRachel BukerAngela Saltarelli, Elizabeth Emerson and Marian Ang, has 555 email subscribers and a searchable database of 461 items. Its scope is broad enough to cover not merely intellectual property law but other areas of legal concern for artists and the art-driven industries. Art & Artifice recently launched a Twitter presence that is followed by over 250 readers.
Revitalised last year and growing in momentum is SOLO IP, which reflects some of the interests, and the anguish, of those who practise IP by themselves or in small groups, or who work in environments in which they are the only IP people ( As of today, this blog -- which is driven by blogmeister Barbara Cookson (Filemot Technology Law Ltd), has 295 email subscribers and a searchable database of 437 items. This blog warmly invites expressions of interest from would-be bloggers (on which see 'Would you like to be an IP Blogger' below)

Would you like to be an IP blogger? Most of the weblogs listed above are still hoping to recruit some fresh talent into their blogging teams, as well as to host more good guest items from occasional writers. If you (i) have something valuable to say about IP, (ii) have some experience of IP in one form or another and (iii) think that you may be able to turn your hand at blogging (or already have some experience), do email Jeremy at, attaching or linking to your CV, and explain why you think you might be a good blogger.

I am willing to bet that the link you give to the Class 99 blog in your article is not accurate... it seems to have content that is only marginally connected to design law (although I have since learnt how to have a v)

I believe there is a mistake in the class 99 blog url:

Thanks, Aaron and anonymous! I've corrected the link.
