Donald L. Jackson

I'll research this attorney before drafting.

Good initial data. Let me dig into the tracked cases and his background.

Donald L. Jackson — Reg. No. 41,090 — patent litigator based in Northern Virginia. Public records (PTAB filings, docket entries, Martindale) consistently identify him as the Donald L. Jackson at Davidson Berquist Jackson & Gowdey LLP, McLean, VA; note a former U.S. district judge and other attorneys share the name.

Specialty / focus. His tracked matters cluster tightly around wireless and remote-monitoring technology: the long-running SIPCO/IPCO (d/b/a Intus IQ) campaigns over low-power wireless transceiver, mesh/remote-monitoring and "IoT"-style patents (e.g., U.S. Patents 6,437,692; 6,914,893; 8,000,314; 8,233,471), litigated against industrial/electrical-equipment maker Emerson Electric and its process-management subsidiaries. His one PTAB docket entry outside that cluster is Unified Patents, LLC v. MYW Semitech, LLC (electronics/semiconductor-related subject matter). Public PTAB records also show him on power-of-attorney filings for Worlds Inc. in 2015 IPRs (3D/virtual-world software). The overall docket reads as electronics and networking rather than pharma or life sciences; mechanical/instrumentation subject matter appears mainly through the Emerson industrial-equipment context.

Side preference. The tracked list is 3 defendant-side to 1 plaintiff-side, and the pattern is operating-company defense: in SIPCO, LLC v. Emerson Electric Co. (lead counsel), SIPCO, LLC et al. v. Emerson Electric Co. et al. (outside counsel), and Emerson Electric Co. v. SIPCO, LLC (of counsel, where his client Emerson was the named plaintiff), he sat on the Emerson/operating-company side of a patent-monetization dispute. His Daignault Iyer appearance as counsel of record in Unified Patents v. MYW Semitech places him on the patent-owner/respondent side against a defensive aggregator, so he is not strictly a one-side practitioner — but the weight of his verified work is defending accused product companies, not prosecuting NPE-style assertion campaigns.

Firm context and notable matters. Most of his verifiable career is at Davidson Berquist Jackson & Gowdey LLP, the McLean, Virginia IP boutique where he is listed as a partner; the tracked record shows him there from at least 2015 through 2019, with a later appearance listed under Daignault Iyer. His most prominent work is the SIPCO–Emerson dispute, which produced significant PTAB and appellate outcomes: the Board cancelled challenged claims in the Emerson CBM (CBM2016-00095) and IPR proceedings, and SIPCO's appeals largely failed — including the precedential Federal Circuit decision in SIPCO, LLC v. Emerson Electric Co., No. 18-1635 (Fed. Cir. Nov. 17, 2020) (holding the CBM institution determination non-appealable under § 324(e) in light of Thryv), and the Rule 36 affirmance in No. 18-1364 (Fed. Cir. Jan. 21, 2021). The district court docket also reflects Emerson's unsuccessful bid for § 1927 sanctions against SIPCO for duplicative forum-shopping. Caution: appellate counsel of record in those appeals were other firms (Ropes & Gray for Emerson), so those results reflect the client's position rather than verified personal argument time.

PTAB/IPR experience. Yes — substantial. Verified filings show him as lead or backup counsel in Emerson-side IPRs (e.g., IPR2015-01579, IPR2017-00007, IPR2017-00252) and as patent-owner-side counsel in the Worlds Inc. IPR filings, i.e., experience on both petitioner and patent-owner sides, plus CBM practice.

Bar / education. Martindale lists B.S.E.E., University of Tennessee (1989); J.D., George Mason University (1998); admitted Virginia 1998; registered before the USPTO; admitted to the Fourth and Federal Circuits and the E.D. Va. These credentials come from a single directory source and were not independently corroborated.
