I
Kilopass and Sidense are competitors in the embedded non-volatile memory (“NVM“) market. Memory cells use transistors to store information. NVM memory consists of memory devices that retain their information (or state) when power is removed. Kilopass markets technology used to create its 1.5T NVM memory technology. Sidense has a competing 1T-Fuse product, the design and technology of which it licenses to its customers, who in turn use those designs to build embedded memory cells.
Kilopass‘s patents cover a memory cell comprised of transistors located at the cross-points of a column bitline and a row wordline. Each transistor has a “gate” connected to a column bitline and a “source” connected to a row wordline. ‘751 patent col. 5 ll. 32-40. Opposite the source is a “drain” that is not connected to any bitlines or wordlines. Id. Beneath the gate is a substrate separated from the gate by a dielectric oxide. Id. col. 7 l. 17. The dielectric oxide is engineered to “break down” when a sufficient voltage is applied to the gate. Id. col. 7 ll. 14-16. If the gate oxide breaks down, a conductive link forms between the source and drain, allowing current to flow through the transistor. Id. col. 7 ll. 16-20. The flow of current indicates that the transistor is in a programmed state, while the absence of current flow indicates that it is in a non-programmed state. Id.
Kilopass‘s ‘751 patent, which is representative of the patents in suit, is directed to a programmable memory cell utilizing a transistor at the intersection of a column bitline and a row wordline. ‘751 patent Abstract. Representative claim 1 reads as follows:
1. A programmable memory cell useful in a memory array having column bitlines and row wordlines, the memory cell comprising:
a transistor having a gate,
a gate dielectric between the gate and over a substrate,
and first and second doped semiconductor regions formed in said substrate adjacent said gate and in a spaced apart relationship to define a channel region there between and under said gate; and wherein the second doped semiconductor region of the transistor is connected to one of said row wordlines,
and wherein said gate dielectric is formed such that the gate dielectric is more susceptible to breakdown near the first doped semiconductor region than said second doped semiconductor region.
Id. col. 14 ll. 30-44 (emphases added).
Claim 1 of the ‘751 patent requires a first and second doped semiconductor region of the memory cell where the second doped region is connected to one of the wordlines. Id. Sidense‘s 1T-Fuse cells, however, utilize a shallow trench isolation (“STI“) region for the transistor drain instead of a first doped region. Kilopass, 2012 WL 3545286, at *10; J.A. 10604. The claim also requires the second doped region to be connected to a row wordline, but Sidense‘s 1T-Fuse product connects the second doped region to the column bitline. Kilopass, 2012 WL 3545286, at *7; J.A. 10604-05. These differences formed the basis of the district court‘s noninfringement determination, which we affirmed. Kilopass, 2012 WL 3545286, at *7-11, aff‘d, 501 Fed.Appx. 980.
II
In 2005, Kilopass‘s founder and an inventor on all three of Kilopass‘s patents, Jack Peng, reviewed an international patent application submitted by Sidense that was directed to protecting Sidense‘s competing 1T-Fuse memory cell. Peng believed that the 1T-Fuse was similar to Kilopass‘s patented cells, except that Sidense used a split gate implementation. Kilopass, 2012 WL 3545286, at *9. Peng contacted a patent attorney at the law firm Perkins Coie to discuss potential infringement. In an email to the Perkins attorney, Peng explained that “[Kilopass] did not file [a] dedicated patent for this split gate implementation” and that “we should [have] ... a long time ago even though we were very busy.” J.A. 10576, 10580. According to Peng, it was not a priority to Kilopass at that time because Sidense‘s “split gate [memory cell] is not self-aligned, so their practical cell size will be larger than [Kilopass‘s] 1.5T cell.” J.A. 10576.
The Perkins counsel nonetheless believed that there was a sufficient basis to challenge Sidense with infringement contentions “in a friendly way ... to see what their reaction is.” J.A. 10578. On November 28, 2005, the Perkins counsel sent a letter to Sidense advising that it “should be interested in obtaining a license to Kilopass‘s patents” or otherwise “provide [Kilopass] with an explanation of how these products avoid the claims” of the patents-in-suit, inter alia. J.A. 10583-86.
Sidense responded on January 20, 2006, stating, “[I]t is our opinion that no products produced by Sidense, nor their methods of operation, fall within the scope of the claims.” J.A. 10590. Specifically, Sidense noted:
[E]ach [claim] require[s] that the transistor have (1) first and second doped semiconductor regions formed in the substrate adjacent the gate; and (2) a second doped semiconductor region connected to the row wordline.... Such elements are not present in Sidense‘s memory cell transistors. For at least these reasons, ... we do not believe any license of these patents is necessary.
J.A. 10590 (emphases added). Sidense also proposed that it was “prepared to consider a third-party examination, on a confidential basis” to confirm whether Sidense‘s products infringed, “provided [Kilopass] agreed to pay the costs of same
After reviewing Sidense‘s response, the Perkins counsel sent the following e-mail to Peng and Kilopass‘s CEO:
Here is my report on Sidense‘s response to our charge of infringement. I still believe given our knowledge of Sidense‘s technology, that they infringe our patents. Please keep in mind that I am assuming that their memory design is the same as detailed in their patent application.... Note that it is possible that Sidense may have changed their memory design to be different from what is shown.... In speaking with Jack [Peng] earlier today, we speculated that Sidense may have eliminated the first doped region and replaced it with a shallow trench isolation [STI] of some sort.... [I]f in fact they have eliminated the first dope region, then they would NOT infringe our claims literally. If that is the case, then we would have to go through a “reissue” proceeding in the patent office that may take 2 years in order to modify our claims to include the situation where there is no first doped region.... The most crucial bit of information we need to find out is the design of their memory cell. We have been ... assuming that their patent application shows their memory cell. This is not always the case and it would be good if we could find out definitively how their memory cell is constructed. I still feel strongly about our case if they are using the memory cell described in their patent application.
J.A. 10601 (emphasis in original). That e-mail made clear that: (1) the analysis by Perkins counsel up to that point had been based on the assumption that the design of Sidense‘s 1T-Fuse cell was the same as the cell described in Sidense‘s international patent application; and (2) if that assumption was incorrect and Sidense had in fact replaced the first doped region (i.e., the drain) with an STI region, then Sidense “would NOT infringe [the] claims literally.” Id.
In June 2007, a Kilopass employee obtained a diagram of Sidense‘s 1T-Fuse cell at a presentation, which confirmed that Sidense had replaced the drain with an STI. The Perkins counsel then sent the following e-mail to Kilopass officials: “My preliminary review of all the Sidense materials indicates that they have redesigned their memory cell to avoid infringement of our patents. Or at least make our case much tougher.” J.A. 10604 (emphasis added). Counsel also noted that Sidense employed an opposite wordline and bitline configuration, viz., the gate of each transistor was connected to a row wordline and the source was connected to a column bitline. Counsel stated that he was “not so worried about the interchange of the bit line and word line,” but that he was “more worried about the fact that [Sidense‘s cell] uses an [STI] on one side of the gate and not a [drain].” Id. at 10604-05.
Despite that advice from its Perkins patent counsel that Sidense did “NOT infringe [the] claims literally,” and that Kilopass‘s case was “much tougher,” Kilopass retained the law firm of Morrison Foerster (“MoFo“) to conduct another analysis. On March 19, 2008, counsel from MoFo emailed Kilopass‘s CEO the following:
As we mentioned during the meeting, assuming Sidense‘s NVM product uses [an] STI region[] (as opposed to two N+ regions) to define the channel below the gate ... Kilopass appears to have a valid claim that Sidense‘s NVM product is at least “equivalent” to the invention claimed by claim 1 of Kilopass‘s ‘751 patent, and therefore that Sidense infringes that patent.
As we also discussed, the next step is for us to conduct a more detailed investigation and analysis to confirm our initial
impressions, which you asked us to complete before your April 2nd meeting with Kilopass‘s Board.
J.A. 11487 (emphases added).
MoFo then immediately began its “more detailed investigation” in order to meet Kilopass‘s deadline. However, eight days later, on March 27, 2008, Kilopass instructed MoFo to stop all work on the project. The reason is unclear, but MoFo subsequently sent Kilopass an invoice for 44 hours of work “relating to Kilopass‘s investigation of potential infringement claims against Sidense.” J.A. 11490. The invoice was accompanied by “a preliminary infringement chart for the ‘751 patent reflecting [MoFo‘s] analysis.” Id.
The infringement chart provided an analysis concerning the doctrine of equivalents and concluded that “Kilopass appears to have a reasonable argument that Sidense‘s field oxide region is equivalent to the doped region in claim 1 of the ‘751 patent, and therefore satisfies this limitation.” J.A. 11497. With regard to literal infringement, the MoFo counsel opined:
[I]f “doped region” is defined as an area on the semiconductor where the electrical properties have been changed, it may be difficult to argue that the field oxide region is a doped region.... If, however, “doped region” could reasonably be defined more broadly as simply an area to which a dopant is applied, then we may be able to argue that the field oxide region is a “doped region.” Determining the potential viability of this argument will require additional investigation, technical feedback from Kilopass and possibly input from an independent expert.
Id.
Although MoFo‘s preliminary infringement chart opined favorably to Kilopass regarding the doctrine of equivalents, there is no evidence in the record that MoFo‘s analysis was complete at that time, nor is there any evidence that Kilopass considered MoFo‘s preliminary infringement chart in deciding to bring suit against Sidense. Kilopass retained MoFo to conduct an infringement analysis but terminated that relationship only eight days later. It does not appear that Kilopass was aware of how much work MoFo had done up to that point or that MoFo was even in the process of completing an infringement chart. In other words, it appears that Kilopass officials had already set their mind prior to learning of MoFo‘s infringement analysis.
In 2008, a team of engineers led by Kilopass‘s CTO sent an exemplary Sidense memory device to a third-party for reverse-engineering. After receiving the results, the CTO created a slide presentation for a meeting of Kilopass‘s board noting that Kilopass had retained the law firm SNR Denton to investigate potential infringement against Sidense. The CTO also stated that Denton “[a]ttorneys don‘t have a conclusion yet as to the reading of 1st doped region and STI region” and that their “formal analysis [was] in progress.” J.A. 11296. However, in the CTO‘s opinion, “[f]rom an engineer‘s perspective,” Sidense infringed under the doctrine of equivalents. Id.
III
On May 14, 2010, Kilopass filed suit against Sidense in the United States District Court for the Northern District of California, alleging both literal infringement and infringement under the doctrine of equivalents.
During the course of the proceedings, the district court discovered that Kilopass was making claim construction arguments to the United States Patent and Trademark Office Board of Patent Appeals and Interferences (the “Board“) that were directly contrary to those being made to the
Additionally, the district court ruled that Kilopass had attempted to amend its infringement contentions and advance previously undisclosed theories under the doctrine of equivalents long past the applicable deadline and without the court‘s approval. Kilopass, 2012 WL 3545286, at *8. The district court noted that “Kilopass‘s assertion of a new theory of equivalence is particularly inappropriate in light of evidence that Kilopass has known for many years that Sidense does not literally infringe its patents.” Id. at n. 8 (emphasis added).
After ruling that Kilopass had disavowed claim scope and striking evidence relating to Kilopass‘s theory of equivalence, the district court granted Sidense summary judgment of noninfringement. Id. at *10. The district court reasoned that Kilopass ignored “numerous differences” between the patent claims and Sidense‘s accused products and that Peng, a named inventor on all three patents in suit, admitted before Kilopass filed suit that Kilopass had actually considered using Sidense‘s design but chose not to because it resulted in a larger cell size. Id. at *9.
Kilopass appealed the district court‘s grant of summary judgment to this court, and we summarily affirmed pursuant to Federal Circuit Rule 36. Kilopass, 501 Fed.Appx. 980. While that appeal was pending, Sidense filed a motion in the district court for an award of attorneys’ fees pursuant to
Although Sidense was the prevailing party on the patent claims, the Court concludes that Sidense has not met its burden of establishing with “clear and convincing evidence” that Kilopass brought or maintained the prosecution of its patent infringement in bad faith. Kilopass performed substantial pre-filing investigation and was able to obtain opinions from two different law firms that Kilopass had a non-baseless claim against Sidense. In addition, Kilopass‘s Chief Technology Officer performed his own independent analysis based on the results of an outside intellectual-property forensics firm to determine that a patent-infringement suit was appropriate.
Kilopass, 2012 WL 6599428, at *3 (citations omitted).
Sidense now appeals the district court‘s denial of its motion for

A determination of whether to award attorneys’ fees under
A case may be deemed exceptional when there has been some material inappropriate conduct related to the matter in litigation, such as willful infringement, fraud or inequitable conduct in procuring the patent, misconduct during litigation, vexatious or unjustified litigation, conduct that violates [Federal Rule of Civil Procedure] 11, or like infractions.
See, e.g., Cambridge Prods. Ltd. v. Penn Nutrients; Inc., 962 F.2d 1048, 1050-51 (Fed.Cir.1992); Beckman Instruments, Inc. v. LKB Produkter AB, 892 F.2d 1547, 1551 (Fed. Cir.1989). Absent misconduct in the litigation or in securing the patent, sanctions may be imposed against the patentee only if both (1) the litigation is brought in subjective bad faith, and (2) the litigation is objectively baseless. Professional Real Estate Investors v. Columbia Pictures Industries, 508 U.S. 49, 60-61 (1993); see also Forest Labs., Inc. v. Abbott Labs., 339 F.3d 1324, 1329-31 (Fed.Cir.2003).
We review de novo whether the court applied the proper legal standard under
Sidense argues that the district court erred in not finding this case “exceptional” under Brooks Furniture because Kilopass‘s claims were objectively baseless and brought in subjective bad faith. In the alternative, Sidense urges us to change the standard for assessing exceptionality under

A
Sidense first faults the district court for its reliance on our decision in MarcTec, LLC v. Johnson & Johnson, 664 F.3d 907 (Fed. Cir.2012), which, in Sidense‘s view, requires too great a showing to establish subjective bad faith. Quoting iLOR, LLC v. Google, Inc., 631 F.3d 1372, 1377 (Fed.Cir.2011), MarcTec stated that, when a defendant seeks fee shifting under
It is unclear whether the district court, in its brief analysis, required Sidense to demonstrate that Kilopass had actual knowledge that its claims were baseless. But, to the extent that the district court did require actual knowledge of objective baselessness, it erred. The language from iLOR and MarcTec that Sidense interprets as requiring actual knowledge does not reflect this court‘s law governing
In addition to any errors the district court may have made by requiring too great a showing of subjective bad faith, the court erred by taking too narrow a view of the proof that can satisfy the subjective prong of the
Our case law has long held that, “in considering a party‘s subjective state of mind, we are ‘to take into account the totality of the circumstances.‘” Highmark, 687 F.3d at 1311 (quoting Mach. Corp. of Am. v. Gullfiber AB, 774 F.2d 467, 473 (Fed.Cir.1985)).
The “should know” rubric obviously applies when a party attempts to escape the consequences of its conduct with the bare statement, “I didn‘t know.” A party confronted with the difficulty of proving what is in an adversary‘s mind must be at liberty to prove facts establishing that that adversary should have known, i.e. to prove facts that render the “I didn‘t know” excuse unacceptable.

The primacy of objective evidence over assertions of subjective good faith or lack of knowledge is well established in our
In discussing the requirement of bad faith to support a finding of exceptionality under
Thus, we vacate the district court‘s judgment denying fees and remand for consideration of whether Kilopass acted in bad faith in light of the totality of the circumstances—with particular attention paid to the objective merits of Kilopass‘s claims and other objective evidence indicative of bad faith.

In 1946, Congress amended the then patent remedy statute, section 4921 of the Revised Statutes of 1874, to state that the “court may in its discretion award reasonable attorney fees to the prevailing party.” Mach. Corp., 774 F.2d at 471 (quoting Patent Act of August 1, 1946, § 1, 60 Stat. 778,
The 1952 Patent Act slightly modified and incorporated the 1946 statute into the present day patent remedy statute,
This section is substantially the same as [the] corresponding provision in R.S. 4921, [except] “in exceptional cases” has been added as expressing the intention of the present statute as shown by its legislative history and as interpreted by the courts.
S.Rep. No.1979, 82nd Cong., 2d Sess. (1952); see also Rohm & Haas Co. v. Crystal Chem. Co., 736 F.2d 688, 691 (Fed. Cir.1984).
Thus, a central aim of
Even Federal Rule of Civil Procedure 11—which allows the imposition of punitive sanctions—does not involve inquiry into a party‘s subjective good faith. Rule 11 allows courts to impose sanctions where a filing contains “claims, defenses, and other legal contentions [that] are [not] warranted by existing law or by a nonfrivolous argument for extending, modifying, or reversing existing law.” Rule 11 functions to assure that parties assert litigation positions that are objectively reasonable at the time of filing. See Hall v. Bed Bath & Beyond, Inc., 705 F.3d 1357, 1372 (Fed.Cir.2013). Importantly, however, Rule 11 does not require a showing of bad faith. See Chambers v. NASCO, Inc., 501 U.S. 32, 47 (1991) (“Rule 11 ... imposes an objective standard of reasonable inquiry which does not mandate a finding of bad faith.“). Because subjective bad faith is not required in the context of Rule 11, it follows that the question of exceptionality under
It does not seem, moreover, that the Supreme Court‘s decision in Professional Real Estate Investors would require that we retain the requirement of subjective bad faith as a predicate to a finding of exceptionality. We cited Professional Real Estate Investors in Brooks Furniture for the proposition that both subjective bad faith and objective baselessness are required under
While Sidense‘s arguments may constitute good faith assertions that our law should be something other than it is, as a panel, we are not able to entertain them. We must, and do, apply our current law, which requires proof of objective baselessness and subjective bad faith as a prerequisite to a finding of exceptionality—the first prong in the court‘s
C
Sidense also contends that it should not be required to prove exceptionality by clear and convincing evidence, as our law currently requires. According to Sidense, proof by a preponderance of the evidence should be sufficient under
We have justified the requirement that a party prove exceptionality by clear and convincing evidence by citing the “presumption that an assertion of infringement of a duly granted patent is made in good
Other cases trace our requirement of clear and convincing evidence with respect to exceptionality under
The pronouncement in Reactive Metals, however, seems to reflect an unneeded expansion of the clear and convincing burden to all aspects of the
Again, while we cannot fault Sidense for making good faith arguments asking that we change our current law, as a panel we may not indulge it. Thus, on remand, the court will apply a clear and convincing evidence standard to the exceptionality component of the
D
Sidense finally urges an even greater overhaul of our standard for assessing exceptionality under
We find this to be Sidense‘s weakest argument for a change in our jurisprudence. As we explained in iLOR,
Section 285 must be interpreted against the background of the Supreme Court‘s decision in Professional Real Estate Investors, Inc. v. Columbia Pictures Industries, Inc., 508 U.S. 49 (1993). There, the Court recognized that the right to bring and defend litigation implicated First Amendment rights and that bringing allegedly frivolous litigation could only be sanctioned if “objectively baseless in the sense that no reasonable litigant could realistically expect success on the merits.” Id. at 60.
631 F.3d at 1376; see also Highmark, 687 F.3d at 1310-11 (explaining that the objective prong is a “single backwards-looking inquiry” that asks whether a reasonable litigant could have expected to succeed in light of the entire record generated in the infringement proceedings). In light of patentees’ First Amendment right to petition the government (by, for instance, filing a lawsuit seeking relief in the courts), we do not think Congress intended to discourage patentees from bringing reasonable claims of infringement by raising the specter of fee shifting—even when the patentee‘s legitimate claims are on less than the firmest ground.
While Professional Real Estate Investors involved the assertion of claims under the Sherman Act, and is, thus, not binding in the patent context, its
Instead, when a plaintiff presses reasonable, but weak, claims of infringement, a prevailing defendant must look to the many other bases for fee shifting under
In sum, we vacate the district court‘s decision denying the motion for attorneys’ fees and remand for consideration of whether Kilopass‘s doctrine of equivalents theory was objectively baseless, and then, whether the totality of the circumstances demonstrates that Kilopass acted with subjective bad faith. If the district court determines that the case is exceptional after applying the correct legal standards, it should then determine, in its discretion, whether to award attorneys’ fees under

Because the district court‘s decision was premised on an incorrect legal standard,
VACATED AND REMANDED.
RADER, Chief Judge, concurring.
I welcome and join the court‘s thoughtful analysis, legal scholarship, and improvement in the application of our fee-shifting law. I also endorse the changes proposed by Sidense that objective baselessness alone should be sufficient for an award of attorney‘s fees, and that proof by a preponderance of the evidence should suffice. Majority Op. at 1312 (“Sidense‘s argument is not without some force.“); Majority Op. at 1314 (“Sidense‘s argument is not a frivolous one.“).
I wish to add to some of the court‘s reasoning with my hope that our court will return to its original binding precedent on fee-shifting. Our earlier jurisprudence governs over the subsequent case of Brooks Furniture. See Newell Cos., Inc. v. Kenney Mfg. Co., 864 F.2d 757, 765 (Fed.Cir.1988) (“[P]rior decisions of a panel of the court are binding precedent on subsequent panels unless and until overturned in banc.“). Before Brooks Furniture, district courts enjoyed broad discretion to shift fees under
I.
As this court notes, in 1946, Congress amended the Revised Statutes of 1874 to state that the “court may in its discretion award reasonable attorney fees to the prevailing party.” Majority Op. at 1312; Mach. Corp., 774 F.2d at 471 (quoting Patent Act of August 1, 1946, § 1, 60 Stat. 778,
This court properly concludes that although the 1952 Patent Act slightly modified the 1946 statute by adding the word “exceptional” and removing the word “discretion,” this change did not depart from the original understanding. Majority Op. at 1312-13. And for a long period of time, this court did just that, reading
During this time, district courts found cases to be “exceptional” in a variety of contexts. For example, “willful or intentional infringement, ... vexatious or unjustified litigation, or other misfeasant behavior” was sufficient. Multiform Desiccants, Inc. v. Medzam, Ltd., 133 F.3d 1473, 1481-82 (Fed.Cir.1998). “[U]nprofessional behavior [was also found to be] relevant to the award of attorney fees, and may suffice, by [itself], to make a case exceptional.” Epcon Gas Sys., Inc. v. Bauer Compressors, Inc., 279 F.3d 1022, 1034 (Fed.Cir.2002).

In 2005, a panel of this court in Brooks Furniture drastically altered this court‘s jurisprudence regarding
As this court notes, Professional Real Estate Investors rests on antitrust concerns that are not present in the
In Christiansburg, the Supreme Court analyzed section 706(k) of Title VII of the Civil Rights Act of 1964. The Title VII language is very similar to the 1946 patent remedy statute. The Court in Christiansburg described section 706(k) as “flexible, authorizing the award of attorney‘s fees to either plaintiffs or defendants, and entrusting the effectuation of the statutory policy to the discretion of the district courts.” Christiansburg, 434 U.S. at 416 (emphasis added). Indeed, the Court expressly determined that subjective bad faith was not a barrier to shifting fees: “[A] district court may in its discretion award attorney‘s fees to a prevailing defendant in a Title VII case upon a finding that the plaintiff‘s action was frivolous, unreasonable, or without foundation, even though not brought in subjective bad faith.” Id. at 421 (emphasis added); see also Fogerty v. Fantasy, Inc., 510 U.S. 517, 534 (1994) (inferring that a prevailing defendant in the context of copyright law can prove even less than a prevailing defendant in Christiansburg to recover fees and holding that fees are within the district court‘s discretion: “There is no precise rule or formula for making these determinations, but instead equitable discretion should be exercised in light of the considerations we have identified.“).
Brooks Furniture, to my eyes, does not fully account for Supreme Court precedent and does not align with decisions of other circuit courts of appeals. For example, the Lanham Act‘s fee-shifting clause,
Thus, in this setting, this court should have remained true to its original reading of
