SLW Institute Presents Patent Analytics webinar series

April 20th, 2020

The SLW Institute began its 8-episode webinar series on Patent Analytics.  The first webinar was entitled “Techniques and Analytics for Identifying Valuable Patents and Patents to Abandon” on April 26, 2020 with subsequent webinars every two weeks.  The panel comprised of Schwegman, Lundberg and Woessner experienced professionals including Steve Lundberg, Principal & Chief Innovation Officer; Janal Kalis, FTO & Patent Analytics Expert; Thomas Marlow, President, Renewals of Black Hills IP and former Chief Patent Counsel of Fairchild Semiconductor; Tyler Nasiedlak, Principal & Former Chief Product Counsel of Guidant Corporation/Boston Scientific and Mark Stignani, Analytics Chair and Firm Compliance Officer and former Chief Patent Counsel of Thomson.

The webinar discussed key concepts in patent value, the difficulty in proactively managing a patent portfolio, but through simple and effective approaches combined with “eyeballs on” review can yield strong results.  Discussions included cross-functional teams, mapping claim coverage to company products and competitor products while considering jurisdiction and age of patents; tagging and classification of a portfolio, including tagging of inventions and disclosures with combined revenue and profit databases; dispositive matrixes; speed and citation analytics for both good and bad patents; automation of USTO patent term calculation as well as a broad array of useful tools across patent search, patent analytics and patent drafting.

Solicitor General Signals Supreme Court to Address the Confusion Caused by the Abstract Idea Exception to 101

December 9th, 2019

While declining to recommend the Supreme Court should grant certiorari in Hikma Pharmaceuticals USA Inc. v. Vanda Pharmaceuticals Inc., the Solicitor General nudged the Supreme Court to reconsider its abstract idea exception established in Bilski and Alice, as follows:

Although Mayo is the most immediate source of confusion, the uncertainty ultimately stems from the broader framework articulated in the Court’s recent Section 101 decisions.  The Court’s reconceptualization in Bilski v. Kappos, 561 U.S. 593 (2010), of inherent, long-recognized limitations on Section 101’s affirmative scope as freestanding, atextual “exceptions,” id. at 601, has given rise to an array of difficult questions.  The confusion created by this Court’s recent Section 101 precedents warrants review in an appropriate case.

While a fix to the 101 confusion would be welcome, there is little hope the Supreme Court could ever deliver it.  Given how metaphysical and generally incomprehensible the abstract idea exception is, nothing short of total disavowal can restore 101 jurisprudence to a sensible state consistent with the rest of the world.  Hopefully Congress will get around to a legislative fix soon.





Why a Machine Readable Computer Instruction is not Abstract

October 21st, 2019

Even after Section 101 gets fixed, we will still be wanting a way to better understand the difference between unpatentable printed matter such as a novel and a patentable computer program consisting of machine readable code.  In my mind, the difference comes down to the essential purpose and value of the former being dependent on variable abstract notions forming in the human mind and essentially only existing in the human imagination, whereas the later’s utility is not in any way dependent on such notions, but rather its 100% predictable and assured activation of an electronic circuit to perform an electronic operation.

Claims of Uniloc Patents Covering a Software Distribution System Found Patent Eligible by Federal Circuit

May 24th, 2019

This post contributed by Eric Bachinski of Schwegman, Lundberg & Woessner, P.A.

Today the Federal Circuit issued an opinion addressing patent eligibility of the claimed subject matter of four Uniloc patents.[1] The Federal Circuit found two of the four representative claims to be patent eligible under the Alice two-step patent eligibility test. The Court distinguished the claims patent eligibility based in-part on whether the claims merely described functional subject matter or whether the claims recited particular improvements over then-existing computer and network functionality.

The first claims addressed by the Court were found to be directed to centralized software distribution. The district court found the claims to be ineligible because the specification described use of the claimed subject matter in the context of an existing software distribution system and considered the claims to be directed to conventional computer functionality. The Federal Circuit found this to be an incorrect analysis of the claims because, while the claims could be used as part of a conventional system, the claims recited an improved software distribution system using file packets in a specific way to accomplish centralized software distribution in an unconventional matter. Thus, the Court found the claimed subject matter reciting a particular improvement to computer functionality not to be directed to an abstract idea under Alice step one. The Court cited to Finjan and McRO to support the conclusion that claims reciting a particular improvement to prior art renders the claims patent eligible.

The second claims addressed by the Court were found to be directed to acquiring a set of user preferences and a set of administrator preferences when launching an on-demand application installation. The Federal Circuit again found that the claims went beyond claiming functionality using conventional computing components and rather recited a using the conventional components in unconventional ways to achieve a particular improvement to computer functionality. The Court cited to Enfish to support the conclusion that such an improvement renders the claims patent eligible. The Court went on to state that even if the claims would have been found to be abstract under Alice step one, the claims still would have been eligible under Alice step two, citing Bascom, as a particular way of using conventional components to achieve an unconventional result.

The third and fourth claims were found to be directed, respectively, to using a desktop interface to access and application server and a license management server that manages client access to an application. Both of these claims were found to be directed to an abstract idea. In the former, the Court found the claims to recite functional use of conventional components. Uniloc argued that the display regions of the interface were unconventional. However, the Court found, citing Intellectual Ventures I LLC v. Capital One Bank, the display regions to be icons that provided conventional functionality and rendered the claims abstract. In the latter, the Court found, citing Elec. Pwr. Grp., that the claims did not go beyond data collection, analysis, and display. There was nothing in the claims that went beyond conventional license management because the Court found the policy, authorization, and notification to operate in a conventional way.

Ancora v HTC America: restriction computer operations with license limitation eligible under Section 101

November 17th, 2018

ANCORA TECHNOLOGIES, INC. V. HTC AMERICA, INC., Appeal Number: 18-1404, November 16, 2018

In this case the Federal Circuit found a method of restricting software operations within a license limitation to be patentable advance, and in particular, the invention was found to be “a concrete assignment of specified functions among a computer’s components to improve computer security, and that this claimed improvement in computer functionality is eligible for patenting. As a result, the claims were found statutory under § 101.

U.S. Patent 6,411,941 is entitled “Method of Restricting Software Operation With-in a License Limitation.”  The ’941 patent describes an asserted improvement based on assigning certain functions to particular computer components and having them interact in specified ways. The proposed method “relies on the use of a key and of a record.” Id., col. 1, lines 40–41. A “key,” which is “a unique identification code” for the computer, is embedded in the read-only memory (ROM) of the computer’s Basic Input Output System (BIOS) module: the key “cannot be removed or modified.” Id., col. 1, lines 45–51. A “record” is a “license record” associated with a particular application: “each application program that is to be licensed to run on the specified computer is associated with a license record that consists of author name, program name, and number of licensed users (for net- work).” Id., col. 1, lines 52–57.

The asserted innovation of the patent relates to where the license record is stored in the computer and the inter- action of that memory with other memory to check for permission to run a program that is introduced into the computer. The inventive method uses a modifiable part of the BIOS memory—not other computer memory—to store the information that can be used, when a program is introduced into the computer, to determine whether the program is licensed to run on that computer. BIOS memory is typically used for storing programs that assist in the start-up of a computer, not verification structures comparable to the software-licensing structure embodied by the claimed invention. Using BIOS memory, rather than other memory in the computer, improves computer security, the patent indicates, because successfully hacking BIOS memory (i.e., altering it without rendering the computer inoperable) is much harder than hacking the memory used by the prior art to store license-verification information. Id., col. 3, lines 4–17; see Ancora, 744 F.3d at 733–34 (“Thus, the inventors stated that their method makes use of the existing computer hardware (eliminat- ing the expense and inconvenience of using additional hardware), while storing the verification information in a space that is harder and riskier for a hacker to tamper with than storage areas used by earlier methods.”).

Here is an example claim from the patent:

1. A method of restricting software operation within a license for use with a computer including an erasable, non-volatile memory area of a BIOS of the computer, and a volatile memory area; the method comprising the steps of:
selecting a program residing in the volatile memory,
using an agent to set up a verification structure in the erasable, non-volatile memory of the BIOS, the verification structure accommodating data that includes at least one license record,
verifying the program using at least the verification structure from the erasable non-volatile memory of the BIOS, and
acting on the program according to the verification.
