Therefore, it is important that patents are written in a way to protect multiple forms of the invention, in particular so that a third party's onshore activities are captured where the law unequivocally applies.

For example, a patent that protects "a kit of parts" may be able to capture a third party's activities at port before the parts are transported offshore for assembly, while a patent that protects a method may capture the third party's activities in preparing the kit of parts for transport.

It will now be particularly interesting to see if Siemens Gamesa appeal this decision and whether any of the judge's conclusions are overturned, especially since the judge's finding on the territorial reach of a UK patent may have a broad impact on patents in this field.
