2 JERRY HARVEY AUDIO HOLDING v. 1964 EARS, LLC

PER CURIAM.

In two inter partes reviews, the Patent Trial and Appeals Board denied Jerry Harvey Audio Holding’s motions 

to amend U.S. Patent Nos. 8,925,674 and 9,197,960 to include proposed substitute claims 22–41 and 19–26, respectively, holding that these claims would have been obvious.

See 1964 Ears, LLC v. Jerry Harvey Audio Holding, LLC, 

No. IPR2017-01091, 2019 WL 1486751, at *26 (P.T.A.B. 

Apr. 2, 2019) (“Board Decision”); 1964 Ears, LLC v. Jerry 

Harvey Audio Holding, LLC, No. IPR2017-01092, 2019 WL 

1486754, at *30 (P.T.A.B. Apr. 2, 2019).1 Jerry Harvey appeals these decisions, arguing that the Board misconstrued 

the claims and that the Board’s alternative obviousness 

findings, which apply Jerry Harvey’s proposed claim construction, are not supported by substantial evidence. Because the Board’s alternative obviousness findings are 

supported by substantial evidence, we affirm the Board’s 

decision.

I

1964 Ears, LLC petitioned for inter partes review of 

Jerry Harvey’s ʼ674 and ʼ960 patents. Both patents describe canalphones2 where a high audio signal is phase corrected with respect to a low audio signal. For example,

claim 1 of the ʼ674 patent, representative of the petitioned

claims relevant on appeal, recites:

1. A system comprising:

1 Because substantively identical decisions were entered in both cases, we hereinafter cite solely to the Board’s

decision in IPR2017-01091. 2 Canalphones “are personal listening devices that 

are substantially smaller than a person’s outer ear.” ʼ960

Patent col. 1 ll. 26–28.

Case: 19-1967 Document: 59 Page: 2 Filed: 04/10/2020
JERRY HARVEY AUDIO HOLDING v. 1964 EARS, LLC 3

a high audio driver carried by a canalphone housing;

a low audio driver carried by the canalphone housing adjacent to the high audio driver; and

an acoustical-timer to phase correct a high audio 

signal from the high audio driver directed to the 

outside of the canalphone housing with delivery of 

a low audio signal from the low audio driver directed to the outside of the canalphone housing. 

ʼ674 Patent col. 12 ll. 30–38.

1964 Ears challenged the claims’ validity based on several references, including U.S. Patent No. 7,317,806 (Harvey ʼ806). Harvey ʼ806 describes a canalphone using two 

drivers, each feeding an output to its respective sound tube 

that then produces an audible output to the user. Harvey 

ʼ806 col. 1 ll. 24–26, col. 1 l. 59–col. 2 l. 5, col. 2 ll. 29–34, 

col. 6 ll. 3–8. When employing two drivers, the canalphone 

splits an input signal at a crossover frequency into a high 

frequency and a low frequency component, where each 

component is then fed to a different driver. Id. col. 1 l. 66–

col. 2 l. 5, col. 3 ll. 46–50. Harvey ʼ806 teaches that frequency division between the drivers causes an unwanted 

phase shift between their outputs that is “inherent” to a

two-driver, frequency-divided design. Id. col. 6 ll. 12–52. 

But Harvey ʼ806 teaches correcting this inherent phase 

shift by optimizing the lengths of the sound tubes receiving 

each driver’s output. Id. col. 6 ll. 37–65. As an example, 

Harvey ʼ806 provides that if the phase shift “inherent in [a] 

specific [canalphone] design is 45 degrees” and “assuming 

that the center of the frequency range of interest is 11.5 

kHz,” then an adjustment in a driver’s sound tube’s length

(an “offset of 3.75 mm”) corrects that phase shift. Id. col. 6

ll. 55–61; see also id. col. 7 ll. 2–7.

After considering 1964 Ears’ petitions, the Board instituted inter partes review of both patents. Jerry Harvey 

Case: 19-1967 Document: 59 Page: 3 Filed: 04/10/2020
4 JERRY HARVEY AUDIO HOLDING v. 1964 EARS, LLC

then filed contingent motions to amend the ʼ674 and ʼ960 

patents to include substitute claims for the Board’s consideration if it held any of the originally petitioned claims unpatentable. The proposed substitute claims modified 

independent claims from each patent, of which the ʼ674 patent’s claim 1 is representative, to further specify “wherein 

the phase corrected response is between 90 degrees and -

90 degrees from 31.5Hz to 16kHz.” Board Decision at *24; 

see also J.A. 396–98 (providing substitute independent 

claims 22 and 30 for the ʼ674 patent), 1797–98 (providing 

substitute independent claim 19 for the ʼ960 patent).

In its Final Written Decisions, the Board found the relevant petitioned claims of the ʼ674 and ʼ960 patents to be 

anticipated or obvious. Next, the Board denied Jerry Harvey’s contingent motions to amend, holding that even under Jerry Harvey’s proposed construction—that the phase 

correction be “through the frequency range from 31.5Hz to 

16kHz”—the proposed substitute claims would be obvious. 

Board Decision at *26. The Board found Harvey ʼ806 to 

teach phase correction over an audible range of frequencies, of which “20Hz to above 11.5kHz” is representative, 

where the two-driver system is less than 45 degrees out-ofphase at its crossover. Id. at *25. And 45 degrees out-ofphase is “less out of phase than 90 degrees,” as the substitute claims require. Id. Thus, the Board concluded that 

the teachings of Harvey ʼ806 “concerning phase correction 

within th[e] range [of audible frequencies] would establish 

prima facie obviousness, which [Jerry Harvey] makes no 

attempt to rebut.” Id. at *26 (citing In re Peterson, 315 F.3d 

1325, 1329 (Fed. Cir. 2003)). The Board therefore denied 

the requested amendment.

Jerry Harvey appeals the Board’s denial of its motions 

to amend. We have jurisdiction under 28 U.S.C. 

§ 1295(a)(4)(A) and 35 U.S.C. § 141(c).

II

Obviousness is a question of law based on underlying 

questions of fact. See Graham v. John Deere Co., 

383 U.S. 1, 17 (1966). Underlying questions of fact include 

the scope and content of the prior art, the differences between the prior art and the claimed invention, and the existence of a motivation to combine prior art references. See

Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 

2015). And in considering prima facie obviousness, 

“[w]hether an invention has produced unexpected results 

and whether a reference teaches away from a claimed invention are questions of fact.” In re Peterson, 315 F.3d at 

1328. We review the Board’s legal decisions de novo and 

its factual determinations for substantial evidence. See

Belden, 805 F.3d at 1073. Substantial evidence “means 

such relevant evidence as a reasonable mind might accept 

as adequate to support a conclusion.” Consol. Edison Co. 

v. N.L.R.B., 305 U.S. 197, 217 (1938).

On appeal, Jerry Harvey argues that the Board’s alternative obviousness findings applying Jerry Harvey’s proposed construction are not supported by substantial 

evidence. To start, Jerry Harvey argues that Harvey ʼ806 

fails to teach a “phase corrected response between 90 degrees and -90 degrees from 31.5Hz to 16kHz,” particularly

because 1964 Ears’ expert witness admitted that Harvey 

ʼ806 does not teach how to determine “how much phase 

shift is existing in [a] system.” Appellant’s Br. at 18–19 

(citing J.A. 1539). Assuming Harvey ʼ806’s lack of explicit 

teachings, Jerry Harvey next argues that the Board also 

fails to describe a motivation to produce a phase corrected 

response in the claimed frequency range or a reasonable 

expectation of success in doing so. Appellant’s Br. at 21–

24 (citing Board Decision at *25–26).

We disagree. First, substantial evidence supports the 

Board’s finding that Harvey ʼ806 teaches phase correction 

Case: 19-1967 Document: 59 Page: 5 Filed: 04/10/2020
6 JERRY HARVEY AUDIO HOLDING v. 1964 EARS, LLC

over a frequency range, as Jerry Harvey’s proposed construction requires. See Harvey ’806 col. 6 l. 59 (stating that 

phase correction is performed across a “frequency range of 

interest”). Moreover, Harvey ʼ806 teaches that the phase 

correction performed “compensate[s] for [a] phase shift” of 

45 degrees, which is well within the claimed phase shift 

range of 90 degrees to -90 degrees. Id. col. 6 ll. 55–61. And

contrary to Jerry Harvey’s assertions, whether Harvey 

ʼ806 teaches how to calculate a system’s phase shift is irrelevant to its teachings of phase correction over a frequency range. Thus, because the phase shift and frequency 

teachings of Harvey ’806 are encompassed by the claimed 

phase shift range over the claimed frequency range, Harvey ʼ806 establishes prima facie obviousness. See In re Peterson, 315 F.3d at 1329 (“In cases involving overlapping 

ranges, we and our predecessor court have consistently 

held that even a slight overlap in range establishes a prima 

facie case of obviousness.”). A patent owner may overcome 

a prima facie case of obviousness by showing that a claimed 

range achieves unexpected results or that the prior art 

teaches away from the claimed range. See id. at 1330–31.

But Jerry Harvey “makes no attempt to rebut” the prima 

facie obviousness. Board Decision at *26. 

Substantial evidence also supports the Board’s findings 

on reasonable expectation of success and motivation to produce the claimed phase corrected response. Foremost, as 

recognized by the Board, Jerry Harvey admits that phase 

correction across the claimed frequency range can be 

achieved through routine experimentation. See Board Decision at *25 (citing J.A. 719 (Jerry Harvey admitting at 

IPR hearing that phase correction “as defined in the patent” is “something that basically has to be played with in 

Case: 19-1967 Document: 59 Page: 6 Filed: 04/10/2020
JERRY HARVEY AUDIO HOLDING v. 1964 EARS, LLC 7

the lab” and is not “beyond routine experimentation”))3; see 

also In re Ethicon, 844 F.3d 1344, 1350 (Fed. Cir. 2017) 

(holding that “an explicit teaching, suggestion, or motivation in the references is not necessary to support a conclusion of obviousness”). And if routine experimentation 

provides for optimizing the phase shift across a frequency 

range, then we find a motivation to produce a phase corrected response in the claimed frequency range and a reasonable expectation of success in doing so.

Thus, substantial evidence supports the Board’s findings that, applying Jerry Harvey’s proposed claim construction, Harvey ʼ806 renders the proposed substitute 

claims obvious. We therefore need not consider the Board’s 

alternative obviousness finding based on U.S. Patent Application 2011/0058702. See Board Decision at *26. Similarly, we need not consider the Board’s construction of the 

proposed substitute claims. See id.

III

We have considered Jerry Harvey’s remaining arguments and find them unpersuasive. Because substantial 

evidence supports the Board’s finding that Jerry Harvey’s 

proposed substitute claims would have been obvious, we affirm the Board’s decisions.

AFFIRMED

3 Jerry Harvey’s admission that the claimed range 

was nothing more than routine experimentation also further supports our earlier finding that the claimed range itself would have been obvious.
