Intellectual Property Listings
The listings on this directory cover intellectual property service providers, law firms, licensing professionals, and IP-adjacent real estate practitioners operating across the United States. Each entry represents a distinct professional or organizational entity active in the intellectual property sector. This reference exists to support researchers, property professionals, and service seekers in locating qualified practitioners and understanding how IP services intersect with real estate and asset management frameworks. For broader context on how this directory fits within the larger IP reference landscape, see the Directory Purpose and Scope page.
How to use listings alongside other resources
Directory listings function as a locator layer, not a standalone advisory resource. A listing identifies a provider, their practice area, and their geographic service footprint — it does not substitute for direct professional engagement or regulatory verification.
The United States Patent and Trademark Office (USPTO) maintains the definitive public registry of licensed patent practitioners under 37 CFR Part 11, which governs the rules of practice before the USPTO. Any practitioner listed in this directory who holds USPTO registration can be independently verified through the USPTO's publicly searchable Patent Practitioner database. State bar associations maintain parallel records for attorneys practicing trademark or IP litigation.
Listings are most effective when used in conjunction with primary regulatory databases. For example, a real estate professional managing portfolio assets that include patented improvements or licensed technologies should cross-reference any practitioner listing here against USPTO registration status and state bar standing before engaging services. The How to Use This Intellectual Property Resource page provides structured guidance on navigating the full scope of available reference materials.
How listings are organized
Listings are categorized along 3 primary classification axes:
-
Practice type — Patent prosecution, trademark registration, copyright licensing, trade secret protection, IP due diligence for real estate transactions, and IP portfolio management are treated as distinct practice categories. A single firm may appear under multiple categories if it actively practices across disciplines.
-
Practitioner credential class — USPTO-registered patent agents (non-attorney practitioners permitted to prosecute patent applications under 37 CFR § 11.6) are classified separately from patent attorneys, who hold both USPTO registration and a state bar license. Trademark specialists who are attorneys but not USPTO-registered patent practitioners occupy a third credential class. This distinction matters in real estate IP contexts, where licensing agreements for proprietary construction methods or building technologies may require patent prosecution expertise rather than general trademark counsel.
-
Geographic service scope — National-scope practitioners, regional firms, and single-state operations are tagged accordingly. Firms headquartered in one state that hold multi-state bar admissions or practice before federal agencies (USPTO, the International Trade Commission) are classified as national-scope.
Within each category, entries are ordered by completeness of verified credential information, not by commercial priority.
What each listing covers
A standard listing entry contains the following data fields:
- Entity name — The registered business name or individual practitioner name
- Practice category — One or more of the classification types described above
- Credential identifiers — USPTO registration number (where applicable), state bar number, and issuing jurisdiction
- Service geography — States or federal districts where the practitioner actively accepts engagements
- Specialty focus — Where disclosed, a notation of sub-specialty such as architectural IP, proptech patent prosecution, real estate technology licensing, or commercial lease IP auditing
Patent agents and patent attorneys are distinguished explicitly in each entry because the scope of authorized practice differs materially. Under 37 CFR § 11.5, a registered patent agent is authorized to represent applicants before the USPTO but cannot provide legal advice on litigation, licensing contract enforceability, or state law matters. An attorney who is also a registered patent practitioner carries both authorities. For transactions involving IP embedded in real property — such as patented building systems, licensed HVAC technologies, or proprietary property management software — the correct credential class is a functional selection criterion, not a formality.
Trade secret practitioners present a different classification challenge because trade secret protection in the United States is governed by two overlapping frameworks: the federal Defend Trade Secrets Act (DTSA), enacted in 2016 under 18 U.S.C. § 1836, and individual state statutes, 48 of which have adopted versions of the Uniform Trade Secrets Act (UTSA) as compiled by the Uniform Law Commission. Listings for trade secret specialists note whether the practitioner holds demonstrated experience under federal DTSA claims, state UTSA jurisdictions, or both.
Geographic distribution
IP service providers in this directory are distributed across all 50 states, though practitioner density reflects the historical concentration of patent prosecution work in technology and manufacturing corridors. States with the highest USPTO-registered practitioner populations include California, New York, Texas, Virginia, and Illinois, consistent with USPTO geographic data published in its annual Performance and Accountability Report.
For real estate-specific IP practitioners — those who specialize in proptech licensing, construction patent disputes, or smart building technology agreements — practitioner availability is more concentrated in metropolitan markets with active commercial construction and technology development sectors: San Francisco, New York City, Chicago, Dallas, and Washington D.C.
Listings flagged for national-scope service include practitioners admitted to practice before the USPTO and federal courts across multiple circuits, which is relevant for IP matters tied to real property assets held in multi-state portfolios. Single-state listings are appropriate for matters governed primarily by state property law intersecting with local licensing agreements or trade secret claims under a specific state's UTSA enactment.
The full set of active listings, searchable by practice category and geography, is accessible through the Intellectual Property Listings index. Gaps in geographic coverage reflect practitioner participation rates rather than population data, and the directory is updated on a rolling basis as new credential-verified entries are submitted and reviewed.
