Sеrio-US Industries, Inc. (Serio-US) sued Plastic Recovery Technologies Corp. (PRT) in the United States District Court for the District of Maryland for infringement of claims 1-3 of United States Patent Number 5,094,358 (’358 patent) and claim 1 of United States Patent Number 5,662,364 (’364 patent). PRT counter-claimed against Serio-US for state law tortious interference and unfair competition, and Lanham Act violations (§ 43(a)). Following a jury trial, the trial court entered a judgment of non-infringement in favor of PRT. Serio-US Indus., Inc. v. Plastic Recovery Tech, Corp., No. WDQ-03-1382 (D.Md. Oct. 19, 2004). In addition, the trial court dеnied PRT’s motion for judgment as a matter of law (JMOL) on its counter-claims of Lanham Act violations, tortious interference, and unfair competition. The trial court also denied PRT’s motion for attorney fees under 35 U.S.C. *1315 § 285 and 15 U.S.C. § 1117(a). In its appeal, Serio-US asserts the trial court committed error in admission of particular evidence and on claim construction; PRT cross-appeals the trial court’s denial of its JMOL and 35 U.S.C. § 285 motion. Because the record adequately supрorts the trial court’s claim construction and other rulings, this court affirms.
I.
Serio-US manufactures and sells automatic locks for dumpsters. These “automatic” locks use gravity to open the dumpster as it is lifted by the trash truck. The ’358 and ’364 patents claim these inventions. Serio-US owns the ’358 patent and exclusively licenses the ’364 patent. PRT made and sold a competing lock. PRT had been designing and building its competing lock since approximately 2001.
The ’358 and ’364 patents claim different vеrsions of dumpster-locking mechanisms. Both disclosed a gravity-actuated' dumpster lock that prevents a dumpster from opening until inverted for emptying. Generally, the ’358 patent discloses a “locking mechanism” that is comprised of an L-shaped lockover arm, locking bar, and locking bar rotation arresting means. The ’364 patent generally disclosed a “latching mechanism” comprised of a latching arm, a slide member, a guide member and a trigger means for autоmatically latching said slide member to said guide member.
Figure 6 illustrates the principles of the ’358 patent’s invention:

Serio-US appeals the trial court’s construction of the claim terms “on a front side of said container” and “locking bar rotation arresting means” in claim 1 of the ’358 patent:
1. An automatic pivoting locking mechanism for a dumpster container having a hinged lid, said locking mechanism comprising:
at least one L-shaped lockover arm mounted for рivotal rotation about a pivot axis on a front side of said container;
a locking bar supporting said L-shaped lockover arm for pivotal rotation about said pivot axis on said front side of said container; and
a locking bar rotation arresting means for securing said locking bar in a locking position, said arresting means comprising a swing lever extending from said locking bar which is engageable by a wedge assembly for wedging said swing lever against movement when said container is in an upright position, said wedge assembly releasing said locking *1316 bar to enable rotation about said pivot axis when said container is substantially forwardly pivoted.
In May 2003, Serio-US sued PRT for infringement of the ’358 and ’364 patents and unfair competition under the Lanham Act. In June 2003, the trial court denied .Serio-US’s request for a preliminary injunction.
Serio-US Indus., Inc. v. Plastic Recovery Tech., Corp.,
Serio-US, however, does not appeal the judgment entered by the court. Serio-US instead complains of the trial court’s alleged errors in improperly admitting evidence during the jury trial and the trial court’s alleged errors in claim construction that appear in the jury instructions. Ser-io-US claims that the jury instructions contain claim construction errors. Yet, even though Serio-US submitted proposed jury instructions on the second day of trial, the record does not show that Serio-US objected to the trial court’s jury instructions. Serio-US also .did not move for a JMOL оr a new trial.
Nevertheless, Serio-US argues that the trial court erred by interpreting claim 1 of the ’358 patent as a means-plus-function claim. Serio-US also argues that the district court erred in its construction of “on a front side of said container” (“front side” limitation) and “locking bar rotation arresting means.” Even so, with regard to the ’364 patent, Serio-US does not complain of any specific claim construction. Instead, it broadly complains that the trial court improperly permitted experts to testify about the interpretation of the ’358 and ’364 patent claims and to opine on the ultimate issue of infringement. Thus, Ser-io-US’s complaints about the trial court’s construction of the ’364 patent’s claim are procedural.
Nonetheless, because Serio-US made no Federal Rule of Civil Procedure 50 or 59 motions (JMOLs or motions for new trial) on the ultimate question of infringement, this court affirms because it finds no prejudicial legal errоr. Furthermore, because Serio-US did not object to the jury instructions, which contained the court’s claim interpretations, this court affirms the trial court’s entry of the judgment because it finds no plain error.
II.
The infringement analysis proceeds as a two-step process. “Step one, claim construction, is a question of law, that [this court] reviews de novo. Step two, comparison of the claims to the accused device, is a question of fact, and requires а determination that every claim limitation or its equivalent be found in the accused device.” N. Am.
Container, Inc. v. Plastipak Packaging, Inc.,
A. Jury Instructions
Pursuant to Rule 51, a party must object to jury instructions “before the jury retires to consider its verdict, stating distinctly the matter objected to and the grounds for objection.”
Advanced Display Sys., Inc. v. Kent State Univ.,
In the Fourth Circuit, if a party does not object to an instruction before the jury retires and does not submit desired instructions, it cannot complain on appeal unless it shows plain error, as required under Rule 51(d).
Pogue v. Retail Credit Co.,
Serio-US did not object to the jury instructions as required by Rule 51(c). As a result, it may only appeal plain error, if any, under Rule 51(d). Therefore the only way the Fourth Circuit permits the appeal of a triál judge’s error in jury instructions without an objection lodged at trial is when the record shows “plain error” resulting in a miscаrriage of justice.
Barger v. Mayor & City Council of Balt.,
This court perceives no miscarriage of justice. In fact, the jury charge, ’ considered as a whole, “fairly and adequately state[d] the pertinent legal principles,” which in this case is the claim construction in question.
Edens v. Goodyear Tire & Rubber Co.,
B. Claim Construction
This court need only ascertain that the district court’s jury instruction containing its claim construction does not amount to a “miscarriage of justice.” The trial court concluded that “front side” meаns “a location on a front side surface of a dumpster.” Serio-US complains that the trial court erred in limiting the claim term “front side” to only the front side surface. Serio-US argues that the phrase “front side” means the portion of the container “toward the front.” According to Serio-US, the ’358 patent does not use the word “side” to refer to a surface, but to refer to a portion of an object.
A review of the intrinsic evidence in the patent shows the district сourt properly construed the “front side” limitation claim language to mean “a location on a front side surface of a dumpster.” Transcript of Record at 910-912, Serio-US Indus., Inc. v. Plastic Recovery Tech.', Corp., Nos. 05-1106, 05-1143, 05-1306 (Fed. Cir. argued Jan. 10, 2006) (emphasis added). • In claim 8, the patent claims “a pivot shaft circumscribing the locking bar and extending along said front of said container.” ’358 patent, col. 4, 11. 47-49 (emphasis added). In claim 10, the locking mechanism “according to claim 8, further comprise[s] a hole through said locking. bar and said pivot shaft, wherein a lock can be positioned through said hole.” ’358 patent, col. 4, 11. 53-56 (emphasis added). This claim language does not suggest that the district court’s construction would amount to a “miscarriage of justice.”
The specification also does not suggest any such miscarriage. According to the specification, the invention positioned “a lock, to lock the pivot bar in place with respect to the lockover arm, allowing the L-shaped lockover arm to be secured atop a lid of the dumpster container.” ’358 patent, col. 2, 11. 43-46 (emphasis added). Therеfore, because the L-shaped lockover arm is secured atop the lid of a dumpster, and because the L-shaped lockover arm is fixed to the pivot shaft that extends along the front of the dumpster, then the claimed front side is the front side surface.
This court need not consider independently the “locking bar rotation arresting means” limitation. This court finds that the instructions as a whole fairly and adequately stated the pertinent legal principles, specificаlly the claim construction. As a result, this court does not detect any miscarriage of justice. This court affirms the trial court’s claim construction.
C. Request for New Trial
Furthermore, Serio-US asks this court to remand the case to the trial court for “a correct claim interpretation,” and for “a new trial On the issue of infringement .... ” Brief of Plaintiff-Appellant at 61, Serio-US Indus., Inc. v. Plastic Recovery Tech., Corp., Nos. 05-1106, 05-1143, 05-1306 (Fed. Cir. argued Jan. 10, 2006). However, Serio-US did not file a motion for JMOL or new trial. Without a motiоn for JMOL or a new trial after a jury verdict, -this court will only vacate and remand if it finds a prejudicial legal error in the conduct of the trial.
Acoustical Design, Inc. v. Control Elecs. Co., Inc.,
III.
Turning to Serio-US’s appeals of the trial court’s admission of certain evidence, this court must affirm. SerioUS appealed evidentiary rulings made by the trial court during hearings and the jury trial. Serio-US seeks a remand for a new trial because it believes the evidentiary rulings led to a flawed claim construction. Trial courts have the discretion to hear expert testimony in connection with claim construction issues.
See Phillips v. AWH Corp.,
As this court stated recently, “a court should discount any expert testimony ‘that is clearly at odds with the claim construction mandated by the claims themselves, the written description, and the prosecution history, in other words, with the written record of the patent.’ ”
Phillips,
IV.
Regarding PRT’s cross-appeal, the trial court struck PRT’s counterclaims, and denied PRT’s JMOLs on its counterclaims. The trial court also denied PRT’s motion for attorney .fees under 35 U.S.C. § 285 and 15 U.S.C. § 1117(a). PRT argues that Serio-US’s claims of infringement were baseless, and therefore, made in bad faith.. As the basis for attorney fees that it seeks, however, PRT only attacks Serio-US’s behavior during litigation.
*1320 A. Counterclaims
Under the law of the United States Court of Appeals for the Fourth Circuit, this court reviews the dismissal of PRT’s counterclaims without deference.
De’Lonta v. Angelone,
Likewise, because PRT renewed its objection to the dismissal of its counterclaims following a jury trial through a JMOL, this court also applies the Fourth Circuit law. The Fourth Circuit holds that whether a JMOL should have been granted is a question of law requiring
de novo
review on appeal.
Gairola v. Com. of Va. Dep’t of Gen. Servs.,
The trial court found that Serio-US brought its action in reliance on the opinion of patent .counsel. Before filing suit, Serio-US also attempted to communicate with PRT, but received no response. In addition, the trial court noted that its initial ruling on a motion for a temporary restraining order detected a likelihood that Serio-US would succeed on the merits of its infringement claims against PRT. Thus, the record amply supports the trial court’s rulings.
(1) State Law Counterclaims
However, despite ample support in the record, this court has held that federal patent law preempts state-law tort liability for a patentholder’s good faith conduct in communications asserting infringement of its patent and warning about potential litigation.
See, e.g., Zenith Elecs. Corp. v. Exzec, Inc.,
In its counter-claim, PRT asserted causes of action for unfair competition in violation of the Lanham Act (§ 43(a)), and state common law tortious interference and unfair competition claims. The only factual assertions contained in PRT’s counterclaim refer to Serio-US’s “statements to the garbage industry and trade generally and to its customers and PRT’s customers specifically stating that PRT’s product infringes the ’358 and ’364 patents.”
Therefore, with regard to PRT’s state-law claims, they survive federal preemption only to the extent that those claims are based on a showing of “bad faith” action in asserting infringement.
Zenith,
A patentee that has a good faith belief that its patents are being infringed violates no protected right when it so notifies infringers. Accordingly, a patentee must be аllowed to make its rights known to a potential infringer so that the latter can determine whether to cease its allegedly infringing activities, negotiate a license if one is offered, or decide to run the risk of liability and/or the imposition of an injunction.
Va. Panel Corp. v. MAC Panel Co.,
(2) Lanham Act Unfair Competition Counterclaim
With regard to PRT’s Lanham Act unfair competition counterclaim, Federal Circuit law also applies.
Zenith,
B. 35 U.S.C. § 285 “Exceptional Case” Attorney Fees
PRT appeals the trial court’s refusal of attorney fees under section 285. This court applies Federal Circuit law to the issue of attorney fees in patent infringement cases.
Special Devices, Inc. v. OEA, Inc.,
Exceptional cases usually feáture some material, inappropriate conduct related to the matter in litigation, such as willful infringement, fraud or inequitable
*1322
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.,
As previously noted, the trial court noted that its initial assessment of the merits of Serio-US’s case found a likelihood of success on infringement.
Serio-US,
The trial court did not entertain oral argument or issue any opinion explaining its reasoning.
See Superior Fireplace Co. v. Majestic Prods. Co.,
Thus, the record as a whole in this case adequately supports the denial of attorney fees. This court detects no clear error in the trial court’s factual findings, and no abuse of discretion in its denial of attorney fees. As a result, this court, affirms the trial court’s denial of PRT’s 35 U.S.C. § 285 attorney fees.
COSTS
Each party shall bear its own costs.
