Despite public misconceptions to the contrary, software is not patentable. Of course, aspects of software, or “software related” patents exist in which an otherwise statutory apparatus or product is claimed that includes computer implemented functionality. In an effort to enhance the “quality” of these software related patents, the USPTO issued a notice last Thursday in the Federal Register entitled: Request for Comments and Notice of Roundtable Events for Partnership for Enhancement of Quality of Software Related Patents.
I myself don't understand this, but it sounds interesting. It continues,
Reading through the tea leaves, the USPTO appears quite interested in exploring means-plus-function claiming with the software community. Since this style of claiming directly links the disclosed structure of the patent specification (algorithmic in the case of computer implemented features), it may be that the Office is proposing to rein in the scope of software claims by requiring the more narrow claim type.
