Definition
The Commissioner of Patents is the presidentially appointed federal officer who heads the United States Patent Office (later the Patent and Trademark Office) and exercises statutory authority over the examination, granting, and administration of patents. The Commissioner reviews patent applications, decides questions of patentability on appeal from examiners, issues patents in the name of the United States, and administers the regulatory and procedural rules governing patent practice.
The title and scope of the office have shifted over time. In its modern form, the function is carried out by the Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office, with subordinate commissioners for Patents and for Trademarks handling day-to-day operations. Historical legal sources use "Commissioner of Patents" to refer to what was then a single, unified office head — a usage that does not map cleanly onto the current organizational structure.

Recognized Forms
/SUBTYPES
Pre-1836 Office: Before the Patent Act of 1836, no Commissioner existed. A clerk in the State Department — commonly called the Superintendent of the Patent Office — handled patent administration on a largely ministerial basis. Patents were issued without substantive examination of patentability, and the Superintendent held no authority to reject applications on their merits.
Commissioner of Patents (1836–1975): The Patent Act of 1836 created the Commissioner of Patents as a distinct statutory officer with authority to examine applications and determine patentability. This is the figure described in all three historical dictionaries and the form most commonly encountered in pre-twentieth-century legal sources.
Director of the USPTO / Commissioner for Patents (post-1975, reorganized 2000): The American Inventors Protection Act of 1999 restructured the Patent and Trademark Office into a performance-based government organization. The title "Commissioner of Patents" was replaced at the top level by "Under Secretary of Commerce for Intellectual Property and Director of the USPTO," with a subordinate "Commissioner for Patents" handling operational oversight of patent examination. Research in post-2000 sources must account for this divided structure.

Why It Matters in Research
The single most important navigational point: the term "Commissioner of Patents" appears across roughly 165 years of American patent law, but it does not refer to the same office or the same powers throughout that span. Researchers encountering the Commissioner of Patents in pre-1836 materials are actually reading about the State Department clerk/superintendent — a functionally different role with no patentability review authority. The 1836 Act is the dividing line that created the Commissioner as a decision-making officer, and legal arguments about what the Commissioner could or could not do must be anchored to which era is at issue.
In nineteenth and early twentieth century case law and treatises, the Commissioner of Patents appears frequently as a quasi-judicial officer whose decisions on patentability could be appealed to federal courts. The nature of that appellate relationship — how much deference courts owed the Commissioner's technical determinations — was contested and evolved considerably. Researchers tracing the administrative law dimensions of patent examination should treat the Commissioner's historical decisions as an early example of specialized agency adjudication.
For corpus research in Law Mind, the Bouvier entry is the most historically detailed of the three sources and is the only one to identify the pre-1836 transition from superintendent to commissioner. Black's and Rapalje & Lawrence state only the bare office description. Neither captures the post-1975 or post-2000 reorganizations, so readers relying on historical dictionaries alone will have an incomplete picture of the current structure.
Be alert to the distinction between the Commissioner acting in an administrative capacity (rulemaking, fee-setting, procedural regulation) versus a quasi-adjudicative capacity (deciding patentability disputes, interference proceedings, and appeals from examiners). The legal standards and review mechanisms differ, and historical sources sometimes blur the line.

Historical Dictionary Support
All three dictionaries define the Commissioner of Patents as simply the head of the Patent Office, a consistent and uncontroversial point of agreement. Black's and Rapalje & Lawrence stop there, treating the office as self-explanatory. Bouvier's is more instructive, noting both the pre-1836 predecessor role and the critical limitation of that earlier function: the superintendent "was not required to decide upon the patentability" of applications — a detail that pinpoints the 1836 Act as the moment the office acquired its most legally significant power.
What all three sources miss, by necessity of their era, is any discussion of the USPTO reorganization or the bifurcation of the Commissioner role. They also do not address the Commissioner's role in relation to the Board of Patent Appeals and Interferences (now the Patent Trial and Appeal Board), which became an increasingly important structural feature of patent administration in the twentieth century. Researchers should use the historical dictionaries to establish the foundational office and its pre-twentieth-century powers, then consult updated statutory and regulatory sources for the modern structure.

Jurisdictional Note
The Commissioner of Patents is a creature of federal law exclusively. Patent authority is a federal constitutional power, and no state officer holds equivalent jurisdiction. International researchers should note that analogous offices — such as the European Patent Office's President — operate under distinct legal frameworks with no direct equivalence to the Commissioner's statutory role under Title 35 of the United States Code.
