Weiss Arons

I'll research this firm before drafting.

Weiss & Arons LLP — Patent Litigation Profile

Firm overview. Weiss & Arons LLP (docketed in some filings as "Weiss Arons") is a small intellectual property boutique headquartered at 63 South Main Street, Spring Valley, New York, in Rockland County, with an additional Rockland County address in Pomona, NY (1540 Route 202) and a reported recent expansion into South Florida. The firm was founded in 2007 and its own materials describe it as a full-service IP practice — patent and trademark prosecution, opinions, transactional diligence, monetization counseling, and enforcement — serving clients ranging from small companies to multi-billion-dollar corporations. It is not an AmLaw-ranked firm and no Chambers or Vault IP ranking could be verified; third-party business-data aggregators estimate roughly 13 employees and low-single-digit-millions in annual revenue, figures that are unverified and should be treated as approximate. The accurate descriptor is a regional IP boutique with a litigation capability, not BigLaw.

IP litigation specialty. The firm's litigation and PTAB work clusters around medical devices and wound-care technology, with a secondary emphasis in electronics. Joel Weiss's published focus areas include analog and digital circuitry, semiconductor processing, and medical devices, and the firm markets technical depth in medical devices, telecommunications, fintech, and pharmaceuticals. Its most substantial tracked disputes involve negative-pressure wound therapy ("NPWT") dressings and pumps, and its website highlights prior enforcement of transapical TAVI heart-valve technology and consumer-facing patent and trade-dress matters. This is not a Wi-Fi/standards-essential or Hatch-Waxman practice on the public record.

Side preference. The tracked data show two plaintiff-side appearances against one defendant-side appearance, but the practical picture is narrower than that split suggests: the firm acts principally as enforcement and patent-owner counsel. Joel Weiss serves as lead counsel for Wound Healing Technologies Corp. as plaintiff in the underlying infringement action, and the firm is patent-owner counsel of record in the resulting IPR — i.e., on the defensive side of a validity challenge. The single "defendant-side" tracked entry appears under the caption Solventum Corporation v. Wound Healing Technologies, LLC, which likely reflects the same or a closely related dispute (the IPR) rather than an independent defense engagement. The firm is therefore best characterized as a patent-owner enforcer for a small client base, not a volume defense shop for operating companies and not an NPE/PAE litigation factory.

Notable tracked matters. The flagship tracked dispute is Wound Healing Technologies Corp. v. Solventum Corporation et al., No. 6:24-cv-00589-RP (W.D. Tex., filed Nov. 15, 2024), in which the firm's client asserted U.S. Patent No. 10,639,404 (a hydrocolloid-based wound dressing) against 3M Company and Solventum, the 2024 healthcare spinoff of 3M. The court granted Solventum's opposed motion to stay the case in favor of PTAB review — an adverse result for the firm's client, though the stay order noted the litigation was at a very early stage with no scheduling order, discovery, or claim construction. Publicly reported outcomes for the firm's other matters are favorable: its site states that the PTAB denied Live Nation's Post-Grant Review petition against Complete Entertainment Resources' U.S. Patent No. 9,466,035 (following a district-court antitrust suit), and that a TAVI patent it prosecuted for Endoheart AG (U.S. Pat. No. 8,182,530) was asserted against Edwards Lifesciences in the District of Delaware, drawing two Edwards IPR requests. The firm has also reported more recent PTAB wins and successful reversals of examiner rejections.

PTAB / IPR practice and key personnel. The firm maintains a genuine but modest PTAB practice, primarily as patent-owner (respondent) counsel defending prosecuted patents rather than as a high-volume petitioner. In Solventum Corp. v. Wound Healing Technologies Corp., IPR2025-01042, the Board instituted review of all claims of the '404 patent; third-party PTAB trackers report the proceeding as terminated-settled as of August 2026, though I could not independently confirm the settlement through a court or PTAB opinion. Total firm-wide IPR/PGR volume is not publicly reported, and the public record shows activity concentrated in a handful of matters tied to a small client base — no reliable scale figure should be asserted. The practice leaders are Joel Weiss (managing partner; registered patent attorney, Reg. No. 44,398; J.D., University of Pennsylvania, 1997; admitted in New York, the USPTO, the Federal Circuit, and the S.D.N.Y./E.D.N.Y.; repeatedly listed in Super Lawyers for IP) and Edward M. Arons, Ph.D. (founding partner; Reg. No. 44,511), both of whom are named in the tracked appearances. Other attorneys appearing on the firm's matters include Ariel Reinitz (admitted pro hac vice in the W.D. Tex. action) and Evan Schechter (intellectual property and civil litigation).

Sourcing note: the case list above was cross-checked against the PTAB filings in IPR2025-01042, the W.D. Tex. stay order, the Wound Healing Technologies/3M docket, and the firm's own website. The exact relationship between the captions "Wound Healing Technologies Corp." and "Wound Healing Technologies, LLC" is itself disputed in the record (Solventum argued they are different entities), and the characterization of the firm's PTAB practice rests on that limited set of filings.
