On 12 May 2009, the UK Intellectual Property Office (UKIPO)
introduced its “Green Channel“, allowing patent
applications for inventions having an environmental benefit to
receive accelerated search, examination and/or publication.
The opportunity to “jump the queue” and potentially
achieve a granted patent sooner is available at no charge; no
reasons are required and a simple statement, or reasonable
explanation, is sufficient; the UKIPO will only refuse requests
that are “clearly unfounded”.
Between its launch in 2009 and the end of 2021, over
4000 patent applications have been processed through the Green
Channel. The UKIPO searchable database does not provide
details of the inventions for which Green Channel has been
requested, but does provide the owner and title, and the International Patent Classification (IPC), into
which all patent applications are classified according to the
different areas of technology to which they pertain.
You might expect that a substantial proportion of applications
processed through the Green Channel would relate to ocean energy
devices, which would certainly qualify for acceleration. A quick
search of the Green Channel database using just the title of the
invention throws up 24 hits for wave energy devices, and 17 for
tidal energy, a total of 41. Alternatively, a more thorough search
using IPC code F03B (machines or engines for liquids),
sub-categories 7 (water wheels), 13 (power
stations) and 17 (other) produces 98 hits; searching
using E02B (hydraulic engineering) sub-category 9
(water power plants) produces another 2 hits, providing a
slightly higher total of 100 hits for patent applications relating
to wave and tidal energy.
Although the methods used to produce these figures are
undoubtedly less then completely accurate, the number of applicants
using the Green Channel for wave and tidal energy devices still
seems surprisingly low, suggesting that not all applicants in this
field are aware of the possibility to accelerate their patent
applications via the Green Channel route.
Accelerated prosecution in the UK has several benefits. Faster
search and examination may lead to faster grant, and a granted
patent can be enforced against infringers, used to attract
investors and to accelerate prosecution in other jurisdictions via
the Patent Prosecution Highway.
Beyond the possibility of a quick grant, accelerated examination
at the UKIPO provides a patent applicant with a good idea of the
“prior art” in the field – the earlier patents and other
documents cited by the UKIPO Examiner as relevant to novelty and
inventive step. This information may allow the applicant to further
develop their invention before the 12-month deadline for filing
foreign or PCT applications.
In the developing field of ocean energy these benefits could be
crucial, and would certainly help innovators in wave and tidal
energy get the most from their patent applications.
