Method or process claims are relatively easy to write once you know what the core invention is and what is necessary to be included in the claim in order to overcome the prior art. Like all claims, method or process claims must completely define the invention so that it works for the purpose you have identified AND it must be unique when compared with the prior art. By unique I mean it must be new (i.e., not identical to the prior art, a 35 USC 102 issue) and it must be non-obvious (i.e., not a trivial or common sense variation of the prior art, a 35 USC 103 issue). Method or process claims will include active steps to achieve a certain result. In method claims the transition is typically either “comprising” or “comprising the steps of.” While legally there may be some distinction between these two different transitions, both are acceptable.
