Summary: Responses to a new batch of complaints from The Economist over what's increasingly perceived as patents excess (due to maximalists who would have us believe that the more, the merrier)
The Economist attack on patents mentions a number of legitimate problems with the patent system, including reducing the number of unenforced or weak patents. However, some of the proposed solutions, e.g. reducing patent terms and expanding the options for challenging patents without a full blown court case, seem to be unrealistic.
Reducing patent terms is virtually impossible since nearly every country in the world is a party to the Trade Related Aspects of Intellectual Property Rights (TRIPS) agreement, which mandates a 20 year patent term. Amending TRIPS would be far more difficult than amending the US Constitution. Forget it. An alternative solution would be to tinker with maintenance fees payable by patent holders. Before the European Patent Office, maintenance (renewal) fees are payable every year, start the third year after filing an application and reach €2000 by around year 10. If the US adopted a similar system, rather than only charging fees after grant of a patent and making them payable every 4 years, it could have a helpful effect.
As for out-of court options for challenging patents, these may already go too far. Witness the recent activity of Kyle Bass, a well known hedge fund manager, in using Inter Partes Reviews (IPR) before the USPTO to challenge key pharmaceutical patents in order to take advantage of the effects of the challenges on the stock prices of the companies holding the patents. Another way to reduce the number of weak patents would be to raise the quality of examination by making a job as a US Patent Examiner more attractive. This could be achieved by increasing the compensation of Examiners, particularly senior Examiners. The compensation of US Examiners is significantly less than their counterparts at the European Patent Office (EPO). In fact, partners at European law firms have been known to leave their jobs to become Examiners at the EPO. This would be unheard of in the US.
Regrettably, any changes to maintenance fees or significantly impacting the compensation of Examiners would require the most unproductive Congress in history to stir itself from lethargy, which could be an unrealistic proposition.
I haven't read "The Economist" recently, but in points I and II it is absolutely correct, certainly in the fields in which I work. The gaming of the system by big companies is especially egregious. Thankfully the EPO has realised to some extent what's going on and the Examiners involved (I've spoken with some of them) do their limited best to restrict some of the more outrageous cons. However, they are always playing catch-up.
On the far side of the Atlantic, where it sometimes seems that the USPTO selects examiners on the basis of a rather unique blend of incompetence, laziness, stupidity, sheer bloody-mindedness and downright dishonesty, things are often much worse, and these obstructive patents, filed purely for that purpose, block off whole areas of legitimate research and actually impede progress.
The patent system may not be broken, but it is certainly badly distorted and rigged against the little guy.
