The Board denied Corning’s rehearing request and left institution denied for claims 1–4 because the petition did not show a reasonable likelihood of proving obviousness on any asserted ground.

“The burden of showing a decision should be modified lies with the party challenging the decision. The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. Thus, a request for rehearing is not an opportunity merely to disagree with the Board’s assessment of the arguments or weighing of the evidence, or to present new arguments or evidence.” slip op. at 2

“Request for Rehearing (Paper 16, “Rehearing Request” or “Reh’g Req.”) of our Decision denying institution of an inter partes review (Paper 15, “Decision” or “Dec.”) of claims 1–4 of U.S. Patent No. 8,488,115 B2 (Ex. 1001, “the ’115 patent”). In the Decision, we found that Petitioner failed to provide sufficient evidence to show that the choosing limitation of the claims would have been obvious over cited references in view of the knowledge of one of ordinary skill in the art. Dec. 20, 26, 29. We, thus, found that Petitioner did not establish a reasonable likelihood of prevailing in showing that claims 1–4 of the ’115 patent are unpatentable as obvious on any asserted ground.

Petitioner failed to explain why one of ordinary skill in the art at the time of the invention, without using the ’115 patent as a template, would have elected to consider only some selected data in Abbott, while ignoring other data, or would have elected to choose an optical fiber based on such consideration.

“The second part of Petitioner’s first argument is that we “committed legal error by construing claim 1” of the ’115 patent “as requiring the slope to always be negative.” Reh’g Req. 4, 6–8. We made no such construction, either expressly or implicitly. In fact, we determined that no claim term required express construction. Dec. 7. In arguing that we committed legal error, Petitioner points to statements in Patent Owner’s briefing (Reh’g Req. 6–9), but Petitioner identifies nothing in our Decision that indicates we construed the “choosing” limitation of claim 1 to require that the DMD slope always be negative. Consequently, Petitioner’s assertion of legal error is unsupported.” slip op. at 7

Denied Corning’s rehearing request; the Board maintained its denial of institution because the petition did not show a reasonable likelihood that claims 1–4 were obvious on any asserted ground.

In the Decision, we found that Petitioner failed to provide sufficient evidence to show that the combined teachings of the prior art would have rendered obvious the limitation of claim 1 that requires “choosing for use in a communications network those optical fibers in which the result of subtracting the peak delay at the first radius from the peak delay at the second radius is a negative number” (“the choosing step”). Dec. 23–25, 29–30, 32. We, thus, determined that Petitioner did not establish a reasonable likelihood of prevailing in showing that claims 1–4 of the ’027 patent would have been obvious based on any asserted ground.

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
