Subject : Proposed Rules Re Formal Patent Drawings

I write as a patent attorney to voice opposition to the proposed rules lowering standards for formal patent drawings. Interpretation of patent claims is a matter that significantly impacts the public interest. The public should be "on notice" of what subject matter is covered by any given patent, and what subject matters is part of the public domain. Claim interpretation is already much too complicated, even for patents having drawings that meet the current standards. Any reduction in those standards will exacerbate difficulties associated with interpreting the scope of patent claims. Thus, I believe the proposed rules will work a great disservice to the public interest.
