The steps to filing patent include, e.g., determination of the likely new and non-obvious aspects (e.g., by patent search), drafting initial claim set, drafting a specification (description) of the invention in support of the claims, drafting any necessary drawings, review of the application, filing the application, responding to a restriction action from the Patent Office (splitting the application into two or more separate inventions), responding to a first office action on the merits of the case, and responding to a final office action. Claims are often found allowable by the final office action stage. Prosecution can further include, e.g., abandonment of the case, interviews with examiners, filing requests for continued examination, filing appeal briefs, and petitions.
