The fate of Software inventions related to information processing

Rob Raheja | January 28, 2015

Content Extraction and Transmission LLC v. Wells Fargo Bank, N.A. et al.

December 23, 2014

Panel: Chen, Dyk and Taranto.  Opinion by Chen.

Summary

The Federal Circuit held that the claims of the asserted patents were invalid as patent-ineligible under 35 U.S.C.S. § 101 because none of asserted claims amounted “to ‘significantly more’ than the abstract idea of extracting and storing data from hard copy documents using generic scanning and processing technology.”

Surviving Alice Gone Wild

John Kong | November 26, 2014

Before the Supreme Court’s decision in Alice Corp. v CLS Bank Int’l [1], Judge Moore said “this case is the death of hundreds of thousands of patents, including all business method, financial system, and software patents as well as many computer implemented and telecommunications patents.”[2] This concern is premised on about twenty years of patent practice grounded in the en banc 1994 Federal Circuit decision in In re Alappat which previously established the “special purpose computer” justification for patent eligibility under 35 USC §101 for computer-implemented inventions.[3]  The Alice decision essentially eliminated the “special purpose computer” bright line rule as applied generally to computer-implemented inventions.  The new Mayo 2-part §101 test for computer-implemented inventions is, however, fraught with issues from the lack of guidance on how to properly apply it.  Some strategic arguments for surviving a §101 attack are presented in this article, as well as a new way to address what is “significantly more.”

Practical Points From The Supreme Court’s Alice Decision

John Kong | June 26, 2014

Alice Corp. v. CLS Bank Int’l

June 19, 2014

Summary: 

The Supreme Court’s Alice decision does not eliminate software patents as per se ineligible subject matter under 35 USC §101. The Court confirms the application of Mayo’s two step §101 analysis and provides some new considerations for addressing patent eligibility issues for computer-implemented inventions.  Unfortunately, the Supreme Court’s admonition that the mere addition of “conventional” computer functionality to an abstract idea does not transform the claim into patent eligible subject matter conflates the §101 analysis with patentability issues under 35 USC §§102 and 103.

PTAB Finally Considers “Processor” As Clearly Structure

John Kong | June 19, 2014

Ex Parte Cutlip

June 2, 2014

Panel: Lorin, Mohanty and Hoffman.

Summary:

After the debacle of three March 2013 PTAB decisions by a five judge PTAB panel relying on a strange American Heritage dictionary definition of “processor” as being software, this PTAB decision sets the record straight about a “processor” as clearly being structure.

Computer-implemented “control means” requires description of step-by-step algorithm even if not key feature of claimed invention

Nicolas Seckel | April 4, 2012

Ergo Licensing, LLC v. Carefusion 303, Inc.

March 26, 2012

Panel: Newman, Linn and Moore.  Opinion by Moore.  Dissent by Newman.

Summary

Another reminder that under US patent law, a “means-plus-function” element recited in a patent claim covers only the corresponding structures described in the specification and their equivalents.  If insufficient or no corresponding structures are described in the specification, the claim is invalid as indefinite.  The rule is strictly applied even if the functional element is only a peripheral aspect of the invention.  Here, the patent claims were directed to a multichannel drug infusion system.  A “control means” was recited (for controlling the motor that adjusts the drug dosage).  The Federal Circuit affirms the invalidity of the claims.  The specification disclosed a “control device,” but no “step-by-step process.” Since the recited function could not be performed by a general computer without special programming, disclosure of an algorithm was required to avoid “pure functional claiming.”
