RatnerPrestia

I'll research the firm and the tracked case before writing.

Let me dig into the tracked case and firm leadership.

Let me verify McCleary, firm leadership, and rankings/practice pages.

Firm overview. RatnerPrestia, a Professional Corporation, is a U.S. intellectual property boutique founded in 1981 and headquartered at 2200 Renaissance Boulevard in King of Prussia (Valley Forge), Pennsylvania. Its office footprint spans the Philadelphia suburbs (Valley Forge/Berwyn and King of Prussia), Wilmington, Delaware, and Washington, D.C., with an associated office in Munich, Germany — a German connection reflected in the firm's prosecution client list (Porsche, Continental, FANUC, Toray). This is a regional IP boutique, not a BigLaw or AmLaw 200 firm: third-party business databases list roughly 85–250 total employees and Martindale lists 26 lawyers in the Valley Forge office and 4 in Wilmington. I could not verify a current AmLaw, Vault, or Chambers ranking for the firm, so no ranking should be assumed. Martindale peer reviews for the Valley Forge office average 4.2/5.

IP litigation specialty. The firm's own practice description covers the full IP lifecycle — procurement, post-grant proceedings, litigation, licensing/transactions, and IP risk management — for sectors including biotechnology, pharmaceuticals, life sciences, consumer products, telecommunications, and software. Its prosecution docket skews mechanical and electro-mechanical (automotive components, appliances, industrial equipment, consumer goods) alongside chemical/pharma work. That profile matches its only tracked litigation: Baby Jogger, LLC v. Baby Generation, Inc. d/b/a Mockingbird (D. Del. No. 1:24-cv-00725-GBW), a mechanical stroller-accessory case over seat-attachment patents — a consumer-products patent suit rather than a standards-essential or semiconductor dispute.

Side preference. The tracked data is thin and skewed: one appearance, plaintiff-side, zero defendant-side, with RatnerPrestia acting as local counsel in Delaware. That single data point should not be read as an NPE/PAE plaintiff practice — the client, Baby Jogger, is an operating company (a Newell Brands subsidiary), and the case is a competitor-versus-competitor enforcement action. Public Delaware docket records also show the firm appearing for defendants in other matters (e.g., Equinox Payments, Pandigital, and comma.ai), so the firm does not appear to be structurally one-sided; the low tracked count more likely reflects a practice centered on prosecution and counseling with selective litigation support.

Notable cases and PTAB. The most prominent tracked matter is the Newell/Baby Jogger enforcement campaign: Baby Jogger filed parallel suits in 2024 against Mockingbird, Evenflo, and Monahan Products/UPPAbaby asserting five stroller seat-attachment patents (U.S. 8,955,869; 9,403,550; 11,192,568; 11,505,231; 11,878,729), with RatnerPrestia's Valerie F. McCleary listed as local counsel. The defendants counter-attacked at the PTAB with at least six IPRs in 2025 (IPR2025-01095, -01100, -01105, -01106, -01120, -01122, -01140); at least one, IPR2025-01120, was denied institution on discretionary grounds in December 2025. No verdict, appeal, or settlement in the district case has been publicly reported as of this writing. On the post-grant side, the firm does present itself as having a post-grant practice and has represented patent owners before the PTAB (e.g., patent-owner counsel in IPR2016-01428). I found no public report quantifying its IPR/PGR filing volume, so no scale estimate is offered; the firm's PTAB activity appears modest relative to dedicated IPR boutiques.

Key attorneys. Publicly identifiable IP litigation and leadership figures include Benjamin E. Leace, a shareholder and management-committee member who describes litigation as his primary practice and has publicly listed wins including a U.S. preliminary injunction and a declaratory-judgment invalidity/non-infringement result; Paul F. Prestia, a long-serving shareholder and former management chair based in Wilmington; Jonathan Spadt, the firm's President and CEO; and Wilmington-based John W. McGlynn and Jeffrey B. Bove. Note that Valerie F. McCleary, the attorney of record in the tracked case, has a limited public profile and I could not independently verify her role or title beyond the case record.

Sourcing caveat: firm size, revenue, and office-count figures come from business databases (ZoomInfo, Adapt, PitchBook) and Martindale listings that conflict and may be outdated; the firm's own materials reference different office sets over time. Case details are drawn from the D. Del. docket and PTAB filings.
