Claude Opus 4.1 vs o3

The 1984 Supreme Court case **Sony Corp. of America v. Universal City Studios, Inc.** saved the VCR from illegality with a 5-4 decision. MPAA president Jack Valenti famously told Congress in 1982: "I say to you that the VCR is to the American film producer and the American public as the Boston strangler is to the woman home alone." [1][2] The Court's primary justification centered on "time-shifting" - recording programs for later viewing constituted fair use under copyright law. The majority held that Sony could not be liable for contributory infringement because the Betamax had substantial non-infringing uses, particularly allowing viewers to watch programs at more convenient times. [1][3] The 2013 parallel case was **Kirtsaeng v. John Wiley & Sons, Inc.**, decided 6-3. Thai student Supap Kirtsaeng imported and resold textbooks legally purchased abroad at lower prices. [4][5] The Court ruled the first-sale doctrine applies to copyrighted works lawfully made and sold abroad, then imported into the United States. Justice Breyer's majority opinion emphasized that geographical restrictions would create absurd consequences, undermining the doctrine's purpose of preventing copyright holders from controlling downstream distribution after an authorized sale. The ruling affirmed that once a copyright owner sells a product, their control over its distribution ends, regardless of where the initial sale occurred. [4][6] Both decisions significantly limited copyright holders' control over technology and distribution methods, with Sony establishing the "substantial non-infringing use" test and Kirtsaeng confirming the international scope of first-sale doctrine, protecting consumers' rights to use and resell legally obtained products.

1984: Sony Corp. of America v. Universal City Studios, Inc. (“Betamax case”)—5-4 decision [1]. The Court held that private, non-commercial “time-shifting” of free broadcast television with a VCR is fair use and that a device capable of “substantial non-infringing uses” cannot render its maker secondarily liable, so the Betamax remained lawful. At a 1982 Congressional hearing, MPAA president Jack Valenti warned, “I say to you that the VCR is to the American film producer and the American public as the Boston Strangler is to the woman home alone.” [2] 2013: Kirtsaeng v. John Wiley & Sons, Inc.—6-3 decision [3]. The Court ruled that the copyright “first-sale” doctrine in §109(a) applies to copies lawfully made abroad; once the rights holder sells a legitimate copy, the purchaser may resell or import it into the United States without further permission. Justice Breyer’s majority stressed that the statute imposes no geographic limitation and that adding one would disrupt libraries, museums, used-goods markets and technology resale. Both cases limited copyright holders’ control over new technologies and global trade: Sony affirmed consumers’ right to time-shift broadcasts and shielded device makers, enabling the video-rental industry; Kirtsaeng protected downstream resale and parallel importation, allowing global secondary markets for books, media and electronics. Both rulings remain cornerstones of U.S. copyright jurisprudence. ## References [1] Oyez. “Sony Corp. of America v.
