The law behind it
Quoted verbatim from Trade Name Report (Oklahoma General Corporation Act) and Partnership Fictitious Name Certificate (18 O.S. §§ 1140-1140.3; 54 O.S. §§ 81-84.1).
What the law requires
Oklahoma is a state-level filing regime: a business operating under a name other than its legal name files a trade name report with the Oklahoma Secretary of State under 18 O.S. § 1140, and partnerships operating under a fictitious name file a separate fictitious name certificate with the Secretary of State under 54 O.S. § 81. There is no county-level DBA filing.
"A corporation or other business entity doing business in this state under any name other than its legal name shall file a report with the Secretary of State setting forth the legal name of the corporation or business entity, the jurisdiction of organization of the corporation or business entity, the trade name under which the business is carried on, a brief description of the kind of business transacted under the name, and the address wherein the business is to be carried on." — 18 O.S. § 1140(A)
Where filings go
Both the general trade name report (18 O.S. § 1140) and the partnership fictitious name certificate (54 O.S. § 81) are filed with the Oklahoma Secretary of State.
"Except as otherwise provided by law, every partnership transacting business in this state under a fictitious name, or a designation not showing the names of the persons interested as partners in the business, must file for recording with the Secretary of State, a certificate, stating the names in full of all the members of the partnership, their resident street addresses, the state or other jurisdiction of its organization and the physical office address of the partnership." — 18 O.S. § 1140(A); 54 O.S. § 81(A)
Name restrictions
The trade name must be distinguishable on the Secretary of State's records from names of domestic and foreign business entities (existing now or within the preceding three years), other trade names or fictitious names on file, and reserved names.
"The trade name adopted shall be such as to be distinguishable upon the records in the Office of the Secretary of State from: 1. Names of other business entities organized under the laws of this state and filed with the Secretary of State then existing or which existed at any time during the preceding three (3) years; or 2. Names of foreign business entities qualified to do business in this state and filed with the Secretary of State then existing or which existed at any time during the preceding three (3) years; or 3. Trade names or fictitious names filed with the Secretary of State; or 4. Names reserved with the Secretary of State." — 18 O.S. § 1140(A)
Entities and assumed names
The entity-side mechanism is the same § 1140 trade name report (it is written for corporations and other business entities). For name conflicts, 18 O.S. § 1141(3) lets a foreign business entity whose true name is unavailable in Oklahoma qualify by adopting a fictitious name by resolution, used to the exclusion of its true name in the state.
"In the case of any foreign business entity having a name prohibited by this section which intends to qualify to transact business within this state, a resolution adopting a fictitious name not prohibited by this section, which shall be used to the exclusion of its true name when transacting business within this state. Such resolution shall be executed by a representative or representatives of the business entity duly authorized to sign on its behalf." — 18 O.S. § 1141(3)

If you skip it
Partners doing business under an unregistered fictitious name cannot maintain any action on partnership contracts or transactions in Oklahoma courts until the certificate is filed; compliance at any time removes the disability retroactively. (54 O.S. § 83)
