IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF OHIO EASTERN DIVISION

HYTERA COMMUNICATIONS ) CORP. LTD., ) CASE NO.: 1:17 CV 1794 ) Plaintiff. ) JUDGE DONALD C. NUGENT ) v. ) ) MOTOROLA SOLUTIONS, INC., ) ) MEMORANDUM OPINION Defendant. ) AND ORDER )

This matter is before the Court on Plaintiffs Motion for Partial Summary Judgment (ECF #131), and Defendant’s Motion For Summary Judgment of Non-Infringement and No Damages. (ECF #132, 133). Each party filed a response in opposition to the opposing party’s motion, and a reply in further support of their own. (ECF #135, 136, 141, 143). The Court heard oral arguments on the motions on September 21, 2020. (ECF #146). After careful consideration of the briefs and a thorough review of all relevant evidence and authority, the Court finds no infringement. Accordingly, Plaintiff's Motion for Partial Summary Judgment is DENIED, and Defendant’s Motion for Summary Judgement of Non-Infringement is GRANTED. .

FACTS AND PROCEDURAL HISTORY! Hytera Communications Corp., Ltd. (“Hytera”) is the owner of asserted U.S. Patent No. 9,183,846 (“the ‘846 Patent”). The ‘846 Patent protects a method for enhancing the audio output quality of speech for communication devices in noisy environments, by allowing for the automatic adjustment of both volume and audio frequency response in response to ambient noise. According to Hytera, this method is unique in that it requires two distinct gains: a volume adjustment, which is triggered based on the level of ambient noise; and, a frequency adjustment wherein a treble or bass boost, of a gain greater than one, is triggered only when the ambient noise meets a pre-set threshhold. The ‘846 Patent describes the method as follows: A method for adaptively adjusting an acoustic effect, wherein the method is applied to an apparatus having an audio output device, and the method comprises: obtaining an energy value of a current ambient noise; receiving a first triggering instruction, and adjusting a current output volume based on the energy value of the current ambient noise; and performing a treble boost processing if it is determined that the energy value of the current ambient noise is greater than a first threshold, or performing a bass boost processing if it is determined that the energy value of the current ambient noise is smaller than a second threshold

] The facts and procedural history have been taken from the undisputed statements set forth in the parties’ briefs, and official court records. In accordance with the applicable standards on a motion for summary judgment, genuine questions of material fact have been resolved in favor of the non-moving party. -2-

Hytera claims that, beginning in 2014, Motorola Solutions, Inc. (“Motorola”) altered its Intelligent Audio technology to include a “treble boost,” and that this new iteration of Intelligent Audio directly or indirectly infringes the ‘846 Patent. Motorola contends that Intelligent Audio products, do not carry out all of the claimed steps of the ‘846 Patent, and, therefore, are not infringing. Further, Motorola claims that the allegedly infringing technology that is a part of Intelligent Audio existed and was in use prior to the ‘846 Patent. Thus, according to Motorola, if the Intelligent Audio technology does, in fact, carry out all of the claimed steps of the □□□ Patent, its prior existence would invalidate the Patent. There is no dispute that the accused Motorola products constitute apparatuses with an audio output device, which use a method for adaptively adjusting an acoustic effect. (ECF #134, Ex. 2 995; Ex. 5 479). The parties also agree that when it is enabled, Motorola’s Intelligent Audio samples ambient noise and creates a weighted average using 90% past ambient noise, and 10% current ambient noise, which it stores as a variable called “noiseLevel.” (ECF #134, Ex. 103; Ex. 49 371; Ex. 5 9§ 45, 57; Ex. 13 at 33:22-34:21; Ex. 18 4 106). If this “noiseLevel” reaches a certain triggering value, the device adjusts a current output volume by applying a increase to the output signal at the speaker. Hytera calls this a “hardware gain.” Both parties agree that this gain is a change in volume that applies equally to all frequencies. (ECF #134, Ex. 299 114, 117, 120; Ex. 4 §§ 373, 375). It does not result in a relative increase to the either treble or bass frequencies. The parties also agree that the accused technology contains software that checks whether the “noiseLevel” is above a set threshold. (ECF #134, Ex. 2 4 123; Ex. 4 99 387-389). Ifthe “noiseLevel” is above this threshold, and there is speech detected in the output signal, the

¢ 2.

Adaptive Noise Masking (“ANM”) software applies a high-pass filter to the output signal that lowers bass frequencies but does not change the treble frequencies in the output. (ECF #134, Ex. 2 7 138; Ex. 49397). Finally, the parties agree that the Intelligent Audio technology in the Motorola’s products does not have a second threshold that triggers bass boost processing, and the products are not alleged to perform bass boost processing no matter the energy level of ambient noise. (ECF #136, pg. 4).

STANDARD OF REVIEW Summary judgment is appropriate when the court is satisfied “that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” FED. R. Civ. P. 56(c). The burden of showing the absence of any such “genuine issue” rests with the moving party: [A] party seeking summary judgment always bears the initial responsibility of informing the district court of the basis for its motion, and identifying those portions of ‘the pleadings, depositions, answers to interrogatories, and admissions on file, together with affidavits, if any,’ which it believes demonstrates the absence of a genuine issue of material fact. Celotex Corp. v. Catrett, 477 U.S. 317, 323 (1986) (citing FED. R. CIv. P. 56(c)). A fact is “material” only if its resolution will affect the outcome of the lawsuit. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). Determination of whether a factual issue is “genuine” requires consideration of the applicable evidentiary standards. The court will view the summary judgment motion in the light most favorable to the party opposing the motion. Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587 (1986). Summary judgment should be granted if a party who bears the burden of proof at trial

does not establish an essential element of their case. Tolton v. American Biodyne, Inc., 48 F.3d 937, 941 (6" Cir. 1995) (citing Celotex, 477 U.S. at 322). Accordingly, “[t]he mere existence of a scintilla of evidence in support of the plaintiff's position will be insufficient; there must be evidence on which the jury could reasonably find for the plaintiff.” Copeland v. Machulis, 57 F.3d 476, 479 (6" Cir. 1995) (citing Anderson, 477 U.S. at 252). Moreover, if the evidence presented is “merely colorable” and not “significantly probative,” the court may decide the legal issue and grant summary judgment. Anderson, 477 U.S. at 249-50 (citations omitted). In most civil cases involving summary judgment, the court must decide “whether reasonable jurors could find by a preponderance of the evidence that the [non-moving party] is entitled to a verdict.” Id. at 252.
