A Methodical Approach to Patent Claim Drafting

Here is an outline of a methodical approach to patent claim drafting for any area of technology, as discussed in "Structure, Function, and the Spectrum of Patent Claiming:"

  • Carefully identify the advantageous "effect" of the invention
  • Identify the fewest "elements" that will create that effect
  • Start with structure plus function claim type format to link the elements and effects, e.g. "element A for effecting (a, to, with, of, in, on, over) element B"
  • Use dependent claims to "structurally" define elements and/or "functionally" define effects
  • Use "claim-type differentiation" to expand that format with the same elements and effects
  • Use even uncommon claim types for your area of technology
  • Avoid unnecessary "hybrid structural/functional" recitations
  • Appeal rejections that are merely demands for additional structure

Please feel free to contact me for a more-detailed presentation of these ideas to your patent organization, practice group, or class.

Thank you for this, it's so clear. If you have additional materials, I'd like them.

I see that you firm does IP/Patent litigation. Please keep me in mind as a technical expert in software/internet and some other technologies, and
prior art searching.

Why don't you link to where you got this information. These are not your ideas and you should give credit where credit is due.
