Let me verify his firm history and bar/education details.

Let me check his current firm profile and notable case outcomes.

Attorney Summary — Nicholas C. Kliewer

Specialty / focus areas. Kliewer's tracked docket is concentrated in electronics and display technology. The largest cluster is the Innovative Display Technologies / Delaware Display Group assertion campaign and the parallel declaratory-judgment and IPR proceedings against display and consumer-electronics manufacturers (LG Display, LG Electronics, VIZIO, Mercedes-Benz, Apple, K.J. Pretech). A second cluster involves semiconductor image-sensor patents (Collabo Innovations, Inc. v. Aptina (U.S.) Inc. and v. Toshiba Corp. et al., plus related Sony and Delaware actions). His PTAB work adds wireless/cellular standards work (Cellular Communications Equipment LLC), telecom call-processing and correctional-telephony software (Securus Technologies / Global Tel*Link), wearable biometric sensors (Valencell), and automation-middleware patents. No pharma, life-sciences, or mechanical-arts matters appear in the tracked list.

Side preference. Appearances are nearly even — 11 plaintiff-side and 10 defendant-side — but the balance reflects parallel proceedings rather than a genuinely mixed practice. Nearly all tracked appearances were at Bragalone Conroy, a Dallas firm that represents patent owners in monetization campaigns; Kliewer served as back-up counsel for patent owners such as Innovative Display Technologies, Delaware Display Group, and Collabo Innovations, and he was lead counsel for petitioner Securus Technologies in PGR2016-00044. The "defendant-side" entries are largely the mirrored IPR/DJ tracks of those same display-patent disputes, where the client alignment is not always clear from the case caption alone. The fair characterization is a patent-owner/assertion-focused practice with substantial petitioner-side IPR work, rather than a defense practice for operating companies.

Firm context. All 21 tracked appearances are attributed to Bragalone Conroy PC (Dallas). Court filings from 2023–2024 and his Super Lawyers listing place him at Griffith Barbee PLLC (Dallas) in his current practice, which includes IP and commercial litigation beyond patents. No in-house role was identified. Earlier employers listed by third-party data aggregators are not reliably sourced and are omitted here.

PTAB / IPR experience. He is a regular PTAB practitioner, appearing in IPR and PGR proceedings from at least 2014–2018 (e.g., IPR2014-01278, IPR2015-00506, IPR2016-00939, IPR2016-01500, IPR2017-00023, IPR2018-00695), most often as back-up counsel but as lead counsel in the Securus PGR. Notable matters by name include the Innovative Display Technologies display-patent campaign, the Collabo Innovations image-sensor suits, and Securus Technologies, Inc. v. Global Tel*Link Corp. (PGR2016-00044). I could not verify specific verdicts, settlements, or Federal Circuit outcomes for these matters from available sources, so no results are asserted.

Bar / education. Registered patent attorney, USPTO Reg. No. 72,480; State Bar of Texas No. 24083315, admitted 2012; J.D., University of Houston Law Center (2012).
