Dyk
, Circuit Judge.
Intellectual Ventures I LLC (“IV”) sued Symantec Corp. and Trend Micro1 (together, “appellees” or “defendants”) for infringement of various claims of U.S. Patent Nos. 6,460,050 (“the '050 patent”)
, 6,073,142 (“the '142 patent ”), and 5,987,610 (“the '610 patent ”). The district court held the asserted claims of the '050 patent and the '142 patent to be ineligible under § 101, and the asserted claim of the '610 patent to be eligible. We affirm as to the asserted claims of the '050 patent and '142 patent, and reverse as to the asserted claim of the '610 patent.
IV owns the three patents at issue: the '050 patent
, the ' 142 patent, and the '610 patent. IV sued Symantec and Trend Micro, two developers of anti-malware and anti-spam software, for infringement of various claims of those patents. Against Symantec, IV asserted claims 9, 16, and 22 of the '050 patent ; claims 1, 7, 21, and 22 of the '142 patent ; and claim 7 of the '610 patent. Against Trend Micro, IV asserted claims 9, 13, 16, 22, and 24 of the '050 patent ; and claims 1, 7, 17, 21, 22, 24, and 26 of the '142 patent.
With respect to the two defendants, a § 101 patent eligibility issue arose at different stages of the proceedings. The case against Symantec went to trial. The jury found that Symantec had not proven by clear and convincing evidence that any asserted claims were invalid under §§ 102 and 103. The jury found Symantec had infringed the asserted claims of the '142 patent
and '610 patent, and had not infringed any asserted claims of the '050 patent.2 After trial, Symantec brought a motion under Fed. R. Civ. P. 52(c) for a judgment that all the asserted claims of the three patents-in-suit are unpatentable under 35 U.S.C. § 101, an issue not addressed in the jury verdict.
The case against Trend Micro did not go to trial. Trend Micro brought a motion for summary judgment of invalidity under § 101
for all of the asserted claims.3 After Trend Motion had submitted its motion, IV withdrew its assertion of claim 7 of the 610 patent only with respect to Symantec.
The '050 patent
is entitled, “Distributed Content Identification System.” The patent application was filed on December 22, 1999, and the '050 patent issued on October 1, 2002. The patent is directed to methods of screening emails and other data files for unwanted content.
The '142 patent
is entitled, “Automated Post Office Based Rule Analysis of E-Mail Messages and Other Data Objects for Controlled Distribution in Network Environments.” The patent application was filed on June 23, 1997, and the '142 patent
issued on June 6, 2000. The patent is directed to methods of routing e-mail messages based on specified criteria (i.e., rules).
The '610 patent
is entitled, “Computer Virus Screening Methods and Systems.” The patent application was filed on February 12, 1998, and the patent issued on November 16, 1999. The patent is directed to using computer virus screening in the telephone network.
In both cases the district court determined that the asserted claims of the '050 patent
and '142 patent claimed ineligible subject matter under 35 U.S.C. § 101, and granted appellees' motions with respect to those patents. The district court held, however, that Symantec had failed to establish that the asserted claim of the '610 patent is patent-ineligible under § 101, and denied Symantec's motion with respect to that patent.
Final judgment was entered in favor of Symantec and Trend Micro that the asserted claims of the '050
and '142 patents are patent-ineligible under 35 U.S.C. § 101. Id. See Final Judgment Following Jury Trial (“Symantec Final Judgment”), Intellectual Ventures I LLC v. Symantec Corp. , No. 10–cv–1067–LPS, 2015 WL 4967134 (D. Del. March 24, 2016), ECF No. 770 at 2;4 Judgment, Intellectual Ventures I LLC v. Trend Micro Inc. , No. 12–cv–1581–LPS (D. Del. June 17, 2015), ECF No. 234 at 2. This resolved all claims against Trend Micro. With respect to Symantec, the district court entered final judgment in favor of IV that Symantec infringed claim 7 of the '610 patent with damages in the amount of $8 million, and that claim 7 was also not proved invalid by Symantec under 35 U.S.C. §§ 102 or 103, or patent-ineligible under § 101. See Symantec Final Judgment at 2.
IV now appeals the district court's ineligibility determinations with respect to the '050 patent
and '142 patent as to Symantec and Trend Micro, and Symantec cross-appeals the determination of eligibility for the '610 patent. We have jurisdiction under 28 U.S.C. § 1295(a)(1).
We review the grant or denial of summary judgment de novo . See Nicini v. Morra , 212 F.3d 798, 805 (3d Cir. 2000)
(en banc). For the district court's entry of judgment under Rule 52(c), we review the district court's factual findings for clear error and its legal conclusions de novo . See
EBC, Inc. v. Clark Bldg. Sys., Inc. , 618 F.3d 253, 273 (3d Cir. 2010). Patent eligibility under § 101 is an issue of law which we review de novo . See
OIP Techs., Inc. v. Amazon.com, Inc. , 788 F.3d 1359, 1362 (Fed. Cir. 2015).
Section 101 of title 35
defines patent-eligible subject matter. It provides, “[w]hoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor....” 35 U.S.C. § 101. For over 150 years, the Supreme Court has recognized an implicit exception to these broad categories encompassing “[l]aws of nature, natural phenomena, and abstract ideas[, which] are not patentable.” Mayo Collaborative Servs. v. Prometheus Labs., Inc. , ––– U.S. ––––, 132 S.Ct. 1289, 1293, 182 L.Ed.2d 321 (2012) (citation and internal quotation marks omitted); see also Bilski v. Kappos , 561 U.S. 593, 601–02, 130 S.Ct. 3218, 177 L.Ed.2d 792 (2010)
.
and in Alice, the Court set forth a framework for “distinguishing patents that claim laws of nature, natural phenomena, and abstract ideas from those that claim patent-eligible applications of those concepts.” Alice Corp. Pty. Ltd. v. CLS Bank Int'l , ––– U.S. ––––, 134 S.Ct. 2347, 2355, 189 L.Ed.2d 296 (2014). At Mayo/
e step one, a court must “determine whether the claims at issue are directed to one of those patent-ineligible concepts.” Id. The category of abstract ideas embraces “fundamental economic practice[s] long prevalent in our system of commerce,” id. at 2356 (quoting Bilski , 561 U.S. at 611, 130 S.Ct. 3218 ), including “longstanding commercial practice[s]” and “method[s] of organizing human activity,” id. But the category of abstract ideas is not limited to economic or commercial practices or methods of organizing human activity. See
infra .
If a claim is directed to a patent-ineligible concept, the court must proceed to Mayo
/
ce step two, and ask, “what else is there in the claims before us?” Alice , 134 S.Ct. at 2355 (citation and internal quotation citation omitted). Step two is “a search for an inventive concept—i.e. , an element or combination of elements that is sufficient to ensure that the patent in practice amounts to significantly more than a patent upon the ineligible concept itself.” Id. (citation and internal quotation marks omitted).
/
Alice step two, the search is for “an inventive concept sufficient to transform the claimed abstract idea into a patent-eligible application.” Id. at 2357 (citation and internal quotation marks omitted). And “[s]imply appending conventional steps, specified at a high level of generality,” which are “well known in the art” and consist of “well-understood, routine, conventional activit[ies]” previously engaged in by workers in the field, is not sufficient to supply the inventive concept. Id. at 2357, 2359 (citations and internal quotation marks omitted).
The district court held patent-ineligible the asserted claims of the '050 patent
—claims 9, 13, 16, 22, and 24—directed to filtering e-mails that have unwanted content. We agree with the district court. The parties agree that independent claim 9 is representative. It recites:
