Disclosing Numerical Ranges in Patent Applications

How an invention's values, tolerances, and ranges are described in a patent application can shape what that patent ends up covering. Whether a range was adequately captured in the original disclosure is a question that recurs in both prosecution and post-grant proceedings.

Lynch LLP works on patent drafting and prosecution for clients whose inventions turn on specific quantities and ranges, and on the disputes that arise when that support is later contested. How this plays out depends on the specifics of the technology and the record.
