Opinion

RADER, Chief Judge.

After a trial, the United States District Court for the Southern District of California denied American Technical Ceramics Corporation’s (“ATC”) motions for judgment as a matter of law (“JMOL”) and in the alternative a new trial on validity and infringement of U.S. Patent No. 6,816,356 (“the '356 patent”). Presidio Components, Inc. v. Am. Technical Ceramics Corp., 723 F.Supp.2d 1284 (S.D.Cal.2010); Presidio Components, Inc. v. Am. Technical Ceramics Corp., No. 3:08-CV-00335, 2010 WL 3070370 (S.D.Cal. Aug. 5, 2010) (“Post-JMOL Order”). ATC appeals these decisions. Presidio Components, Inc. (“Presidio”) cross-appeals the district court’s denial of a permanent injunction, JMOL on willfulness, and its ongoing royalty rate and false marking determinations. Presidio, 723 F.Supp.2d 1284; Post-JMOL Order, 2010 WL 3070370. This court affirms the vast majority of the district court’s determinations set forth in its comprehensive and attentive opinions with the exception of its finding of no irreparable injury, the related denial of a permanent injunction, and the ongoing royalty determination. This court also vacates the district court’s false marking judgment due to an intervening change in law. For the reasons below, this court affirms-in-part, vacates-in-part, and remands.

I.

Presidio is a family-owned niche manufacturer of electrical components for high-tech applications. It is operated by Dan Devoe and his two sons Alan and Lambert. The Devoes are the three listed inventors on the '356 patent, entitled “Integrated Broadband Ceramic Capacitor Array.” ATC, a subsidiary of AVX Corporation, manufactures electrical components. ATC’s 545L capacitors, a variety of monolithic broadband capacitors, compete with *1355 Presidio’s Buried Broadband capacitor (“BB capacitor”). At trial, Presidio asserted that ATC’s 545L capacitors infringe the '356 patent.

Capacitors are passive electronic components used in numerous electrical systems including consumer electronics, mobile phones, and audio amplifiers. These capacitors typically filter ripples or spikes in a power supply and store energy to provide a charge to other components on a printed circuit board.

A traditional capacitor comprises two parallel metal plates separated by a dielectric material, such as a ceramic or air. Because the dielectric material is not conductive, a positive charge accumulates on one plate with a negative charge on the opposite plate. The capacitor may release this stored energy by connecting the two plates through a conductive path that closes the circuit. The amount of energy a capacitor can store is its “capacitance,” which depends on the orientation of the metal plates and the properties of the dielectric material.

Frequently, multiple capacitors are combined to create a “multilayer capacitor.” A multilayer capacitor has several layers of conductive and non-conductive materials stacked together. Each layer has its own electrical properties that affect the overall performance of the multilayer capacitor. Capacitor design is a compromise between capacitance, resistance, and inductance. These designs become more complicated as operational frequencies increase in broadband products. In addition to layering, capacitor design typically must also accommodate mounting on a circuit board. A capacitor designer must further consider manufacturing costs and size restrictions. For example, the capacitors in this dispute are tiny — about the size of the tip of a sharpened pencil. They are relatively inexpensive and produced in quantities of several thousand per batch.

The '356 patent claims a capacitor design with a lower frequency portion and a higher frequency portion, for use in broadband applications. The patent teaches a multilayer integrated network of capacitors electrically connected in series and in parallel. This network of capacitors is disposed within a “substantially monolithic dielectric body,” as shown in Fig. 10A. The invention incorporates both electrical and mechanical aspects. Conductive plates 10 and 11 extend from conductive contacts 12 and 13 on opposite sides of a ceramic dielectric body. This structure creates a capacitance between the internal plate combinations 10 and 11 in the upper section 60. At the same time a fringe-effect capacitance arises between external contacts 72 and 74 in the lower section 62 of the device. '356 patent col. 7 11. 20-60.

On the mechanical side, the invention uses a “one-piece” design — an improvement over previous “two-piece” designs. A two-piece design, such as shown in Fig. 8A, had to be joined both together and to a circuit board through soldering or an epoxy. This time-consuming process yielded a less reliable product that in turn was more difficult to use in mass production of end products.

Presidio asserted claims 1-5, 16, 18, and 19 of the '356 patent against ATC. Independent claim 1 is representative and recites as follows:

1. A capacitor comprising:
a substantially monolithic dielectric body;
a conductive first plate disposed within the dielectric body;
a conductive second plate disposed within the dielectric body and forming a capacitor with the first plate;
a conductive first contact disposed externally on the dielectric body and electrically connected to the first plate; and
*1357 a conductive second contact disposed externally on the dielectric body and electrically connected to the second plate, and the second contact being located sufficiently close to the first contact to form a first fringe-effect capacitance with the first contact.

According to inventor Lambert Devoe, the '356 patent covers and protects one of Presidio’s main products, the BB capacitor. The BB capacitor is a monolithic capacitor used in fiber optic network amplifiers and other broadband frequency applications. Another inventor, Dan Devoe, also testified that the '356 patent covered the BB capacitors. Based on this belief, Presidio marked the BB capacitors with a reference to the '356 patent. During this litigation however, Presidio conceded that the '356 patent did not cover the BB capacitors. Nonetheless, Presidio maintains that the BB capacitors have a “substantially monolithic dielectric body,” as shown in Fig. 10A of the '356 patent.

Presidio filed the application leading to the '356 patent with the U.S. Patent and Trademark Office (“PTO”) in April 2003. This application was a continuation-in-part of an application filed in 2002. The '356 patent issued in November 2004. In September 2003, ATC filed a provisional patent application for its work on the 545L broadband capacitor. After reviewing Presidio’s published patent application in March 2004, ATC proceeded to file its non-provisional application in September 2004.
