Definition
MARK carries three distinct legal meanings that rarely intersect in practice. Researchers should identify which sense applies before proceeding.
1. Signature mark. A character — traditionally an X or crossed lines — made by a person who cannot write, serving as a legally recognized substitute for a handwritten signature on deeds, wills, contracts, and other instruments. The mark is executed between the signatory's given name and surname, which a third party writes out on either side, with the words "his mark" or "her mark" inscribed above the symbol. Witnesses typically attest to the making of the mark. When properly executed, a mark has the same legal force as a full handwritten signature.
2. Trademark / trade mark. A symbol, word, design, device, or combination thereof that a producer or seller uses to identify goods or services and distinguish them from those of competitors. In this sense, "mark" is often shorthand for trademark, service mark, certification mark, or collective mark. Modern intellectual property law treats the mark as a form of property, protectable by registration and enforceable against infringement and dilution.
3. Historical territorial unit. In medieval Germanic law, the mark (German: Mark) was a defined tract of land held in common by a community of cultivators. Bounded and recognized by the community, it typically comprised a village, arable land, and common waste or woodland. This sense appears in historical land tenure scholarship and early German legal sources but has no operative modern application.
4. Monetary unit. In old English and Saxon law, a mark was a unit of account — originally a silver coin worth 13 shillings and 4 pence in English reckoning, or 30 pence in the Saxon period. This meaning appears almost exclusively in historical documents, early case law, and fee schedules predating decimalization.

Common Language
Modern common usage (Wiktionary): To put a mark on something; to label, indicate, or leave a lasting impression.
Historical common usage (Webster's 1913): Webster's 1913 redirects "mark" in its legal usage to "marque," referencing a license of reprisals — reflecting the contemporaneous legal significance of letters of marque.
The everyday sense of "mark" as any visible symbol or indication overlaps loosely with all four legal meanings but maps cleanly onto none of them. In particular, the common understanding that a mark is informal or preliminary (as in "marking something up") is almost the opposite of its legal significance in the signature context, where the mark is a solemn and final act carrying full legal weight.

Common Confusion
Three confusions recur in research:
First, mark (signature) vs. mark (trademark): Source documents prior to the 20th century often use "mark" unqualified. Context — conveyancing record vs. commercial registry — is the only reliable guide.
Second, mark vs. marque: Letters of marque (a license to privateers) occasionally appear in historical indices simply as "mark." Webster's 1913 reflects this conflation. They are unrelated legal concepts.
Third, mark (monetary) vs. deutsche mark vs. historical mark coin: Burrill's definition of mark as a Saxon silver coin of 30 pence differs from the later English reckoning of 13s. 4d. (two-thirds of a pound). Neither corresponds to the modern German currency of the same name. Monetary figures expressed in "marks" in historical instruments require identification of the governing period and jurisdiction before conversion.

Recognized Forms
/SUBTYPES
In intellectual property law, "mark" encompasses several formally recognized subtypes:
- Trademark: identifies the source of goods.
- Service mark: identifies the source of services.
- Certification mark: certifies that goods or services meet defined standards of quality, origin, or other characteristics (used by a certifying entity, not the producer).
- Collective mark: used by members of an organization, cooperative, or association to identify membership or shared origin.
- Trade dress: the overall commercial image or appearance of a product, increasingly treated as a form of mark.

Why It Matters in Research
The signature-mark sense is critical in any pre-20th-century document research. Wills, deeds, and contracts executed by illiterate parties — a substantial portion of the population in earlier centuries — bear marks rather than signatures. A mark's validity depended on attestation requirements that varied by jurisdiction and period. Researchers examining the execution of historical instruments must understand what a mark was, how it was recorded, and what attestation law governed at the time to assess enforceability or authenticity.
In trademark research, the shift in American law from common-law protection based on use to a dual system of use plus federal registration (Lanham Act, 1946) creates a significant corpus discontinuity. Pre-1946 materials discuss mark rights primarily through unfair competition and passing off doctrine. Post-1946 materials layer statutory registration, constructive notice, and incontestability on top. Historical dictionaries are largely silent on the post-Lanham framework.
The territorial and monetary senses of mark surface primarily in historical land tenure scholarship, medieval English legal history, and early chancery records. Researchers working in those areas should treat "mark" as ambiguous until context resolves which sense governs.
Geographic indications and certification marks form a growing area of modern IP law with significant transatlantic divergence; see the encyclopedia cross-reference above.

Historical Dictionary Support
The historical dictionaries agree on the signature-mark sense with unusual consistency. Black's (both editions) and Anderson's describe the mechanics of mark-making identically: two crossed lines in the space between Christian name and surname, flanked by "His" above and "Mark" below, with the full name written by a third party. Bouvier adds historical depth, noting that in Saxon times even literate persons were expected to append the mark of the cross as a token of good faith — meaning the mark's original function was attestation and solemnity, not illiteracy. This is a genuinely useful historical point that Black's omits.
Bouvier's treatment of the territorial mark (the Germanic community land unit) is the most complete among the shelf sources and the only entry to address this sense at length. It is absent from Black's and Anderson's, suggesting they treated it as outside the common-law practitioner's reference needs.
Burrill's contribution is primarily the monetary sense, with reference to Coke on Littleton and Spelman's glossary. Burrill distinguishes the Saxon mancus (30 pence) from the later English mark (13s. 4d.) — a distinction none of the other shelf sources draw with precision.
No shelf source addresses the trademark sense in its modern form. This is expected given their dates of publication, but it means the historical dictionaries are nearly useless for intellectual property research on marks and should not be cited for that purpose.

Jurisdictional Note
In trademark law, the United States follows a use-based system supplemented by federal registration, while the European Union and many civil law countries follow a registration-priority system. The term "mark" in international IP materials may therefore carry different priority and ownership implications depending on the governing system. For signature marks, validity requirements — number of witnesses, form of attestation, whether a mark suffices for particular instruments — historically varied by English county, American state, and instrument type.
