Everyone in the intellectual property community will be aware that the debate over the activity of “patent trolls” has lasted years, and has always contained plenty of heat and not a lot of light. The heat shows no sign of diminishing, as journalists realise that there’s an easy story to file in a day trip to Tyler or Beaumont to look at a corridor of brass plated doors with no-one behind them – but there are at least some attempts to shine a light under the bridge to see what these trolls really look like. The latest of these is the recently announced proposal for a collection of information by the Federal Trade Commission (the FTC).
There has been little unanimity on what a patent troll is – except than that no definition ever covers the commercial activity of whoever is making the definition. It has even been difficult to find a neutral generic term for such behaviour. We used to use NPE (“Non Practising Entity”), to distinguish patent owners only interested in licensing from patent holders who used patents to support their own commercial activity in selling products and services. This term fell out of use when it was appreciated that one class of NPEs is long established, generally respected, and considered by most to be behaving in an acceptable way with its stock of intellectual property – such NPEs are often known as “universities”.
Unusually, I’m lost for words. Not words in general, as you can see, but specific words to describe the phenomenon of self-collision between parent and divisional applications identified in European practice by Malcolm Lawrence and Marc Wilkinson of Avidity IP as the poisonous… I’d better stop there. In the light of UK Trade Mark Registration No. 2612561, I think we need to find a new generic term. “Putrid Priority” is often the real problem but as a term, this doesn’t sound like an improvement. It would be good to make some reference to the overarching phenomenon of self-collision. How about “divisional collision”? Why not – let’s see by the end of the article whether it trips off the tongue well enough as we consider its application in in Nestec S.A. et al v. Dualit Limited et al.
IEEE 802.11 is a set of standards that cover wireless local area networking. These standards provide the basis for wireless network products which use the Wi-Fi brand (yes, it is a brand) – most people reading this article will use such technology many times a day. Patents have played a contentious role in the development of this standard, particularly in the successful licensing campaign carried out by the Australian national science agency CSIRO. This campaign has attracted strong criticism – for example in this Ars Technica article - and also some robust defence, particularly from Australia in this piece from the Patentology blog. While clearly no-one likes to be told that they are governed by trolls, hopefully tempers have now cooled, and this is all water under the bridge.
Most patent attorneys at some point in their career will have been introduced to the “Hand Test”. This is a rule of thumb (well, four fingers and a thumb) test to determine whether a claim is useful. There are various versions, but a familiar one is for Claim 1 of a patent to be printed out – for the sake of argument and objectivity, let’s say in 12 point Times Roman with one-and-a-half spacing – and for a patent attorney (let’s say one taking size 8 in gloves) to try to cover it with their hand laid flat, with fingers together, on the paper over the printed claim. If there are lines of text showing above or below the hand, the claim is generally not infringed by the embodiment of interest, avoidable by one simple workaround or another, or simply impossible to infringe.
