What follows is an opinion from a United States Court of Appeals.
Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 

Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)". Your task is to classify the scope of this business into one of the following categories: "local" (individual or family owned business, scope limited to single community; generally proprietors, who are not incorporated); "neither local nor national" (e.g., an electrical power company whose operations cover one-third of the state); "national or multi-national" (assume that insurance companies and railroads are national in scope); and "not ascertained".

Opinion:
PAUL L. DODDS COMPANY, a corporation, Appellant, v. HARRY LISS & ASSOCIATES, INC., et al., Appellees. HARRY LISS & ASSOCIATES, INC., et al., Cross-Appellants, v. PAUL L. DODDS COMPANY, Cross-Appellee.
Nos. 21360, 21360A.
United States Court of Appeals Ninth Circuit.
Oct. 2, 1967.
Jack E. Hursh, Mellin, Hanseom & Hursh, San Francisco, Cal., for appellant and cross-appellee.
Robert D. Hornbaker, Mahoney, Halbert & Hornbaker, Santa Monica, Cal., for appellee and cross-appellant.
Before BROWNING and ELY, Circuit Judges, and BELLONI, District Judge.
PER CURIAM:
The district court held that claim 5 of Dodds Patent No. 3,003,730 was valid, but that it was not infringed by the Liss device. Both sides have appealed.
Claim 5 of the Dodds patent discloses a cantilever counter stool used in restaurants and like installations. All elements of the patented device are found in Dodds 2400 Cantilever Stool (an unpatented stool admittedly in the public domain when the patent in suit was applied for), except that the patented stool is made adjustable by telescoping the seat support tube into a separate base support tube and inserting a locking device.
Making a known device adjustable rarely involves invention, since adjustability and the means to accomplish it are elements of ordinary mechanical knowledge and skill in virtually every art. See Marconi Wireless Telegraph Co. of America v. United States, 320 U.S. 1, 63 S.Ct. 1393, 87 L.Ed. 1731 (1943); Koochook Co. v. Barrett, 158 F.2d 463, 466 (8th Cir. 1946). It was so in the present case. Prior art Blayney Patent No. 1,254,969 and Straith Patent No. 1,337,103 disclose seats adjustable with respect to a table. Dean Patent No. 612,489, Marty Patent No. 624,232, Schwartz Patent No. 1,379,784, and Tveten Patent No. '2,275,330 accomplished adjustability by the télescoping of metal tubes. The locking device employed in the patent in suit is disclosed in Schwartz Patent No. 1,379,784, Tveten Patent No. 2,275,330, Noble Patent No. 2,816,769, and French Patent No. 879,-842.
We are satisfied that the patented combination would have been obvious to a mechanic of reasonable skill having knowledge of Dodds 2400 Cantilever Stool and the prior art patents referred to. The device disclosed in claim 5 of Dodds Patent No. 3,003,730 fails to meet the requirement of section 103, and the claim is therefore invalid.
Reversed.
