Just a short note to present the option of accelerating green patents in the UK.
The UK IPO allows applicants that have inventions that contributes to the environment to request a preferred treatment.
Examination of patents filed initially in the UK is quick anyway (about 4 months) so the extra haste (an approved green application will normally receive an examination report within a couple of weeks) does not really make a huge difference.
However, for either foreign comapnies or UK companies that filed their application initially in other countries, this option is very valuable, as it results in one of the fastest examination procedures in the world.
Moreover, a green application is not, necessarily, an application that relates directly to an environmental end. The environmental benefit can be secondary, as long as it exists. For example, a patent application that makes the lifetime of battaries longer and saves electricity, can be regarded as a “green invention”.
