MEMORANDUM AND ORDER July 18, 2019 Saris, C.J. INTRODUCTION This is a long-running, acrimonious patent infringement case which is now back before the Court for final disposition following an appeal to the Federal Circuit.1 Plaintiff, the Trustees of Boston University, is the owner of U.S. Patent No. 5,686,738 (the “̕738 patent”). The ̕738 patent relates to the preparation of monocrystalline gallium nitride films via molecular beam epitaxy, which, in short, is a process used in creating semiconductors for LED lights. Defendants are Everlight

Electronics Co., Ltd. and Everlight Americas, Inc. (together, “Everlight”); Epistar Corp. (“Epistar”); Lite-On Inc., LiteOn Service USA, Inc., Lite-On Technology Corp., and LiteOn Trading USA, Inc. (together, “Lite-On” and, collectively with Epistar and Everlight, “Defendants”). Defendants are manufacturers of LED devices that Plaintiff alleges infringe the technology covered by the ̕738 patent. There are currently four interrelated motions before the Court: (1) Plaintiff’s motion to affirm the jury verdict or, in the alternative, to modify the claim construction order or amend its complaint, (2) Defendants’ motion to rescind the Court’s award to Plaintiff of partial

attorney’s fees and costs, (3) Defendants’ motion for attorney’s fees, and (4) Plaintiff’s motion for disallowance of costs.

1 The Court assumes familiarity with the Federal Circuit’s opinion as well as the Court’s prior opinions in this case. See, e.g., Trs. of Bos. Univ. v. Everlight Elecs. Co., 896 F.3d 1357 (Fed. Cir. 2018) (appeal); Trs. of Bos. Univ. v. Everlight Elecs. Co., No. CV 12-11935-PBS, 2016 WL 3962826 (D. Mass. July 22, 2016) (judgment as a matter of law); Trs. of Bos. Univ. v. Everlight Elecs. Co., 109 F. Supp. 3d 344 (D. Mass. 2015) (summary judgment on invalidity); Trs. of Bos. Univ. v. Everlight Elecs. Co., 23 F. Supp. 3d 50 (D. Mass. 2014) (claim construction). After hearing, the Court DENIES Plaintiff’s motion to affirm the jury verdict or, in the alternative, to modify the claim construction order or amend its complaint (Dkt. No. 1872), ALLOWS IN PART and DENIES IN PART Defendants’ motion to rescind the Court’s award of attorney fees (Dkt. No. 1859), ALLOWS IN PART and DENIES IN PART Defendants’ motion for attorney’s fees

(Dkt. No. 1860), and ALLOWS IN PART and DENIES IN PART Plaintiff’s motion for disallowance of costs (Dkt. No. 1850). BACKGROUND I. Pre-Appeal Procedural History Plaintiff originally filed a series of cases against Defendants in 2012. In May 2013, the Court ordered that the cases be consolidated. A jury trial was held between November 2, 2015 and November 19, 2015. The jury found the ̕738 patent to be valid and that Epistar and Everlight willfully infringed it. Following trial, Defendants renewed their motion for judgment as a matter of law and moved for a new trial or remittitur. On July

22, 2016, the Court denied Defendants’ motion as to liability but granted Defendants Epistar and Everlight a new trial as to damages or remittitur. Plaintiff then moved for reconsideration of the Court’s decision as to damages, which the Court also denied. II. Appeal In August 2016, the parties cross-appealed various rulings made by the Court, including the ruling on Defendants’ motion for judgment as a matter of law. On July 25, 2018, the Court of Appeals for the Federal Circuit reversed the Court’s decision on Defendants’ motion for judgment as a matter of law and dismissed

all other pending appeals as moot. On October 12, 2018, the Federal Circuit denied Plaintiff’s requests for re-hearing. The Federal Circuit then issued a formal mandate. The Federal Circuit reversed the Court’s denial of judgment as a matter of law for Defendants on the basis that the ̕738 patent is invalid for lack of enablement. The Federal Circuit described the dispositive issue as follows: The district court construed two terms relevant here. First, it construed “grown on” to mean “formed indirectly or directly above.” Under this construction, claim 19’s growth layer and buffer layer do not have to be in direct contact; there can be intervening layers between them. Second, the district court construed “a non-single crystalline buffer layer” to mean “a layer of material that is not monocrystalline, namely, [1] polycrystalline, [2 amorphous or [3] a mixture of polycrystalline and amorphous, located between the first substrate and the first growth layer.” And, while the district court did not specifically construe “growth layer,” BU does not dispute that “growth layer” includes within its scope a monocrystalline growth layer.

Assuming a monocrystalline growth layer, together these constructions raise six permutations for the relationship between claim 19’s growth layer and buffer layer: (1) monocrystalline growth layer formed indirectly on a polycrystalline buffer layer; (2) monocrystalline growth layer formed indirectly on a buffer layer that is a mixture of polycrystalline and amorphous; (3) monocrystalline growth layer formed indirectly on an amorphous buffer layer; (4) monocrystalline growth layer formed directly on a polycrystalline buffer layer; (5) monocrystalline growth layer formed directly on a buffer layer that is a mixture of polycrystalline and amorphous; and (6) monocrystalline growth layer formed directly on an amorphous buffer layer. The enablement issue in this case concerns this sixth permutation—a monocrystalline growth layer formed directly on an amorphous buffer layer.

Trs. of Bos. Univ. v. Everlight Elecs. Co., 896 F.3d 1357, 1360 (Fed. Cir. 2018).

Defendants’ non-enablement defense had two components: a legal component and a factual component. The legal component turned on what it meant for the “full scope” of the patent to be enabled. Defendants argued that in order to be enabled the patent had to teach a person of ordinary skill in the art (“POSITA”) how to make all six permutations describe above. The factual component turned on whether or not the patent did in fact teach a POSITA how to make a monocrystalline growth layer directly on an amorphous buffer layer. Defendants argued that the evidence at trial established that it was impossible to make a monocrystalline growth layer directly on an amorphous buffer layer. In denying judgment as a matter of law for Defendants, the Court rejected both components of Defendants’ non-enablement defense. In turn, the Federal Circuit reversed the Court on both points. On the law, the Federal Circuit held that “[its] precedents make clear that the specification must enable the full scope of the claimed invention,” which meant that the ̕738 patent had to teach all six permutations. Id. at 1364. On the facts, the Federal Circuit held that “Defendants showed that epitaxially growing a monocrystalline layer directly on an

amorphous layer would have required undue experimentation— indeed, that it is impossible.” Id. Accordingly, the Federal Circuit reversed the Court and ordered judgment for Defendants. III. Post-Appeal Motions Following their success on appeal, Defendants filed a bill of costs with the Court. On September 4, 2018, Plaintiff filed a motion to disallow Defendants’ costs, which Defendants subsequently opposed. On November 14, 2018, Defendants filed a motion to rescind the Court’s award of attorney’s fees and costs and a motion for attorney’s fees. Plaintiff opposed both motions.
