MEMORANDUM OPINION

MARY PAT THYNGE, United States Magistrate Judge.

I. PROCEDURAL BACKGROUND

This is a patent infringement case. Cor-dance Corporation (“Cordance”) and Amazon.com, Inc. and Amazon Web Services, LLC (collectively, “Amazon”) develop software and own patents pertaining to on-line internet-based transaction infrastructures. 1 On August 8, 2006, Cordance filed suit alleging that Amazon’s trademarked “1-Click®” purchasing interface, featured throughout its website, infringed U.S. Patent No. 6,757,710 (“the '710 patent”). On September 7, 2006, Cordance filed its first amended complaint. On October 23, 2006 Amazon filed its answer asserting numerous counterclaims and defenses, including a counterclaim of patent infringement of its U.S. Patent No. 6,269,369 (“the '369 patent”). 2 On November 11, 2007, Cor-dance filed its second amended complaint, which alleged that Amazon’s information storage processes infringed U.S. Patent No. 6,044,205 (“the '205 patent”) and that Amazon’s systems for collecting, retrieving, and presenting product reviews and buyer and seller feedback infringe U.S. Patent Nos. 5,862,325 (“the '325 patent”) and 6,088,717 (“the 717 patent”). 3 Subsequently, Cordance and Amazon stipulated to a dismissal of claims and counterclaims *313 relating to infringement of Cordance’s '205 patent and Amazon’s '369 patent. 4 As a result, by the time this case was tried, the patents in suit were Cordance’s '325, 717, and 710 patents.

A jury trial commenced on August 3, 2009. On August 18, 2009, the jury reached a verdict, finding (1) Amazon does not infringe any of the asserted claims of the '325 and 717 patents or claims 2 and 9 of the 710 patent; (2) the asserted claims of the '325 and '717 patents are not invalid; (3) Amazon infringes claims 1, 3, 5, 7, and 8 of the 710 patent; and (4) claims 1, 2, 3, 5, 7, 8, and 9 of the 710 patent are invalid. The court entered judgment on September 9, 2009. On September 23, 2009, Cordance filed a renewed motion for judgment as a matter of law or, in the alternative, for a new trial. On February 22, 2010, the court granted Cordance judgment as a matter of law that, inter alia, claims 7 and 8 of the 710 patent are not invalid. 5 On March 18, 2010, Cordance filed a motion for permanent injunction or, in the alternative, imposition of an ongoing royalty. 6 On April 23, 2010, Amazon filed its answer to Cordance’s motion for equitable relief along with a motion to strike the declaration of Dr. Shamos submitted in support of Cordance’s motion. 7 Cor-dance’s motion for equitable relief and Amazon’s motion to strike the declaration of Dr. Shamos are addressed in a separate opinion. On May 26 and 27, 2010, a bench trial was held on Amazon’s inequitable conduct and patent misuse defenses. On June 2, 2010, Amazon filed its opening brief on those issues. 8 Cordance answered on June 9, 2010. 9 Amazon filed its reply on June 16, 2010. 10 This is the court’s decision on Amazon’s claims that Cordance is guilty of inequitable conduct and should be precluded from enforcing the '710 patent under that doctrine and the doctrine of patent misuse.

II. INEQUITABLE CONDUCT

A. LEGAL STANDARD

Applicants for patents and their legal representatives owe a duty of candor, good faith, and honesty in their dealings with the United States Patent and Trademark Office (“PTO”). 11 A breach of this duty constitutes inequitable conduct. 12 And if inequitable conduct is established, then the entire patent is rendered unenforceable. 13

To successfully prove inequitable conduct, an accused infringer must present “ ‘evidence that the applicant (1) made an affirmative misrepresentation of material fact, failed to disclose material information, or submitted false material information, and (2) intended to deceive the [PTO].’ ” 14 *314 A threshold level of each element — materiality and intent to deceive — must be proven by clear and convincing evidence. 15 Further, even if the requisite clear and convincing showing of both elements has been made, a court may still choose not to invalidate the challenged patent. 16

The following is the standard for materiality: “information is material when a reasonable examiner would consider it important in deciding whether to allow the application to issue as a patent.” 17 With regard to the deceptive intent prong, “ ‘materiality does not presume intent, which is a separate and essential component of inequitable conduct.’ ” 18 “ ‘[T]he alleged conduct must not amount merely to the improper performance of, or omission of, an act one ought to have performed. Rather, clear and convincing evidence must prove that an applicant had the specific intent to ... mislead [ ] or deceiv[e] the PTO.’ ” 19 Such intent can be inferred from indirect and circumstantial evidence, 20 “[b]ut such evidence must still be clear and convincing, and inferences drawn from lesser evidence cannot satisfy the deceptive intent requirement.” 21 Moreover, “the inference must not only be based on sufficient evidence and be reasonable in light of that evidence, but it must also be the single most reasonable inference able to be drawn from the evidence to meet the clear and convincing standard.” 22

A district court cannot find inequitable conduct unless threshold levels of both intent to deceive and materiality are established by clear and convincing evidence. 23 “Only after adequate showings are made as to both materiality and decep *315 tive intent may the district court look to the equities by weighing the facts underlying those showings.” 24
