Several weeks ago, the United States Court of Appeals for the Federal Circuit shook up the patent world with a somewhat unexpected gift for patent owners, particularly patent owners and applicants seeking software patents. The Court issued an important decision on software patent eligibility in Enfish LLC v. Microsoft.
The opinion by Judge Hughes, who was joined by Judge Moore and Judge Taranto, doubles the total of Federal Circuit decisions where claims in a software patent were deemed to be patent eligible because they are not abstract. In other words, DDR Holdings is no longer the only point of hope for innovators and patent owners in the software space.
This case stared when Enfish sued Microsoft for patent infringement. The patents at issue were U.S. Patent No. 6,151,604 and U.S. Patent No. 6,163,775, both issued in late 2000 and both claiming priority to the same application filed in March 1995. The ’604 and ’775 patents are directed to an innovative logical model for a computer database. A logical model is a model of data for a computer database explaining how the various elements of information are related to one another. Contrary to conventional logical models, the patented logical model includes all data entities in a single table, with column definitions provided by rows in that same table. The patents describe this as the “self-referential” property of the database.
Recently, the United States Court of Appeals for the Federal Circuit issued a decision in Nike, Inc. v. Adidas AG, relating to an appeal from the inter partes review (IPR) of U.S. Patent No. 7,347,011, owned by Nike.
The Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO) granted the IPR petition filed by Adidas AG and instituted inter partes review of claims 1–46 of the ’011 patent. Nike then filed a motion to amend in which it requested cancellation of claims 1–46 and proposed substitute claims 47–50. The PTAB granted the motion to cancel claims 1-46, but denied the motion to substitute claims, as has become the norm in virtually all cases.
On January 29, 2016, the United States Court of Appeals issued a decision in AKZO Nobel Coatings, Inc. v. Dow Chemical Company, relating to an appeal from the United States District Court for the District of Delaware.
Akzo appealed from the district court’s granting of summary judgment that Dow did not infringe the claims of U.S. Patent 6,767,956, either literally or under the doctrine of equivalents. Dow cross-appealed from the court’s conclusion that the claims of the ’956 patent are not indefinite.
Claim 1 of the ‘956 patent was deemed representative and reads as follows:
1. A process for producing a dispersion of a polymer in an aqueous medium in which the polymer is dispersed in an aqueous medium in an extruder at a temperature above 100° C. in an extruder having an outlet
wherein the pressure in the extruder is maintained above atmospheric so that the aqueous medium does not boil characterized by maintaining the pressure above atmospheric for the extruder at the outlet with a pressurized collection vessel and
wherein aqueous dispersion from the extruder has at least 25% by weight of the aqueous medium where the aqueous medium has less than 40% by weight of organic solvent and
wherein the aqueous dispersion enters the outlet and pressurized collection vessel at a pressure above atmospheric so that the aqueous medium does not boil and is subjected to the action of a cooling zone to lower the temperature of the aqueous dispersion to below 100° C. to have an aqueous dispersion with a viscosity below 10 Pa.s.
Last month, the United States Court of Appeals for the Federal Circuit issued a decision in Ethicon Endo-Surgery, Inv. V. Covidien LP, an appeal from the United States Patent and Trademark Office (USPTO), Patent Trial and Appeal Board (PTAB). The dispute arose as the result of a Covidien inter partes review (IPR) petition challenging claims of U.S. Patent No. 8,317,070 (“the ’070 patent”), which is owned by Ethicon. The PTAB granted the petition and the IPR proceeded to a decision on the merits. On the merits, the same panel that determined that the petition should proceed in the first place, found all challenged claims invalid as obvious over the prior art.
Ethicon appealed to the Federal Circuit, arguing that the PTAB’s final decision was invalid because the same Board panel made both the decision to institute and the final decision. Ethicon also argued that the Board erred in finding the claims obvious.
Several weeks ago, the United States Court of Appeals for the Federal Circuit issued a decision in Redline Detection, LLC v. Star Envirotech, Inc., relating to an inter partes review (IPR) challenge brought by Redline challenging the validity of certain patent claims of U.S. Patent No. 6,526,808 (the “’808 patent”).
After deciding to institute the IPR, the Patent Trial and Appeal Board (PTAB) found in favor of the patent owner. Redline appealed the decision of the PTAB to the Federal Circuit, arguing that it was improperly denied the opportunity to submit supplemental information under 37 C.F.R. §42.123(a) and that the PTAB erred with respect to finding that claims 9 and 10 of the ‘808 patent were not invalid.
The ‘808 patent, owned by Star Envirotech, relates to methods of generating smoke for use in volatile and explosive environments. More specifically, the ’808 patent describes methods for generating smoke that enables the presence and location of leaks in a fluid system to be accurately and visually detected depending upon rate of the air flow through the fluid system under test and whether smoke escapes from the system. The invention allows for the more accurate testing of whether automobile emissions are leaking into the environment.
