Opinion

MEMORANDUM AND ORDER

AUDREY G. FLEISSIG, District Judge.

This patent infringement action was filed on November 5, 2009. Following an eight-day jury trial conducted from February 11 to 21, 2013, the jury returned its verdict finding that Defendant Emerson Electric Co. had infringed certain claims of “the '017 patent,” owned by Plaintiffs, and awarding Plaintiffs $311,379 in damages. The patent at issue claims an air conditioning control (the “fan recycling control”), invented by Armin Rudd, which, when incorporated into a thermostat that is installed in a building or home, operates as part of an air conditioning system to periodically activate and deactivate the fan of the system at preselected intervals after the end of the call for heating or cooling.

The suit initially involved another patent for a fan recycling control invented by Rudd, “the '268 patent.” One of Defendant’s counterclaims sought a declaratory judgment that the '268 patent was unenforceable because, during the patenting process, Rudd withheld information from the United States Patent and Trademark [828]*828Office (“PTO”) regarding the scope and content of prior art. On February 9, 2013, two days before trial, Plaintiffs executed a Covenant Not to Sue Defendant for any infringement and/or damages related to the '268 patent. An evidentiary hearing was held on February 21, 2013, before the Court only, on Defendant’s allegation of inequitable conduct.

Now before the Court are two post-trial motions: (1) Defendant’s motion (Doc. No. 492) for a finding that Plaintiffs engaged in inequitable conduct during the prosecution of the '268 patent by misrepresenting the scope of prior art, and during this lawsuit by pursuing the claim of infringement of that patent, entitling Defendant, under 35 U.S.C. § 285, to attorney’s fees it incurred related to that claim; and (2) Plaintiffs’ motion (Doc. No. 500) for a determination that Defendant’s infringement of the '017 patent prior to the filing date of this lawsuit was willful, thereby entitling Plaintiffs to enhanced damages under 35 U.S.C. § 284.

For the reasons set forth below, the Court finds that Defendant is not entitled to attorney’s fees incurred in defending the claim of infringement of the '268 patent, and that Defendant cannot be found to have been a willful infringer of the '017 patent during the period prior to the filing of this action.

BACKGROUND

The accused products are eight models of Emerson thermostats that have a “Comfort Circulating Fan Feature.” On the first day of trial, the Court granted Defendant’s motion in limine to exclude Plaintiffs’ evidence that Plaintiffs had engaged in “marking” its products that incorporated the '017 patent and had thereby provided Defendant with constructive notice of the patent prior to the date this action was filed. Other than the alleged “marking,” Plaintiffs provided no notice of their infringement claims to Defendant prior to filing suit.

Defendant’s defenses at trial included that the accused products’ fan activation feature did not use the '017 patent, but rather the prior art technology of another patent, the “Vogelzang” patent; that a combination of prior art patents, including Vogelzang, rendered the '017 patent obvious, and therefore, invalid; and that Plaintiffs lacked evidence that the accused feature in Defendant’s thermostats was ever used in an infringing manner by anyone.

The record shows that the application for the '017 patent was filed on January 5, 1995. There is evidence in the record, though not conclusive evidence, that in July 1995, Honeywell, Inc., a competitor of Defendant’s, introduced nationwide the Honeywell PC8900 thermostat, a thermostat that caused the fan to run periodically, beginning a set period of time after the end of the call for heating or cooling. The '017 patent issued on August 20, 1996. Later that year, Rudd sent Defendant a copy of the patent. In April 1997, Rudd tested the Honeywell PC8900 because, based upon the PC8900 Product Data and Owner’s Guide (both dated 1995), he thought it might infringe the '017 patent. Based on his tests, he determined that it did infringe the '017 patent, and he informed Honeywell of such on July 22, 1997.

On March 15,1999, Rudd filed the application that became the '268 patent, claiming priority to a patent application filed on August 18, 1997. He submitted the Product Data, Owner’s Guide, and Product Brochure related to the PC8900 to the PTO, but did not file the test results he had obtained in April 1997. In the application, Rudd represented, as was then required by the PTO, that he did not know or believe that his invention was in public use or on sale in the United States more than [829]*829one year prior to the application.1 On August 13, 2002, the '268 patent issued. On November 20, 2002, Rudd sued Honeywell for infringement of the '017 patent. This suit was settled on March 12, 2003, pursuant to which Honeywell took a license under the '017 patent and an option for a license under the '268 patent. (Doc. No. 313-1.)

Evidence was presented at trial that in 2005, Defendant decided to develop a thermostat to compete with the 2004 Honeywell VisionPRO, a thermostat with a touchscreen, as well as many other features, including a fan recycle feature. Defendant believed that the fan recycle feature of the VisionPRO used the Vogelzang patent and upon inquiry, was told by a member of its legal department (who became a lawyer two years later) that because the Vogelzang patent had been abandoned, the technology was available for use. Defendant decided to go ahead with its new thermostats, including the accused products.

At the February 21, 2013 hearing on the claim of Plaintiffs’ inequitable conduct, Rudd testified that the literature about the Honeywell PC8900 thermostat that he submitted to the PTO in connection with the '238 patent application clearly indicated to anyone skilled in the art, including patent examiners, that the PC8900’s fan began to cycle at a predetermined time after the end of the heating or cooling cycle, as did his claimed invention.

The Jury’s Findings on Royalty Rate and Willfulness

By agreement of the parties, the jury was instructed that November 5, 2009, the date the lawsuit was filed, was the date for the start of damages and that Defendant sold a total of 138,391 accused thermostats from that date until April 30, 2011. This end date for damages was agreed to by Plaintiffs and was based on the only disclosures they had made in their trial materials and expert reports.

The jury was instructed as follows on the question of willfulness:

If you find that it is more likely than not that Emerson infringed at least one claim of the '017 patent, then you must also determine if this infringement was willful. Willfulness means that it is highly probable that:
1. Emerson was aware of the '017 patent,
2. Emerson acted despite an objectively high likelihood that its actions infringed a valid patent, and
3. This objectively high likelihood of infringement was either known or so obvious that it should have been known to Emerson.
