Understanding 35 U.S.C. §112 for Software Patents

Practice tip
Focus on concrete technical mechanisms, not business goals.
Written description
35 U.S.C. §112(a) requires that the specification contain a written description of the invention. For software patents, this means you must describe the technical implementation—algorithms, data structures, and system architecture—in enough detail that a skilled artisan would recognize you possessed the invention at the time of filing.
Enablement
The specification must teach how to make and use the invention without undue experimentation. For software, this often means providing pseudocode, flowcharts, or detailed descriptions of key algorithms. Vague references to "known techniques" may not suffice.
Definiteness
Claims must particularly point out and distinctly claim the subject matter. Avoid purely functional language without structural support. Terms like "configured to" or "adapted to" should be grounded in the specification.
