Claude Opus 4.1 vs DeepSeek V3.2

The 2013 Supreme Court case is Kirtsaeng v. John Wiley & Sons, Inc., where Thai student Supap Kirtsaeng imported and resold textbooks purchased abroad. This case is frequently analyzed alongside the 1984 Sony Corp. of America v. Universal City Studios, Inc. (the "Betamax case") as both pivotal rulings strengthened the first sale doctrine [1][2]. The 1984 Betamax ruling established that time-shifting television programs for personal viewing constituted fair use, protecting VCR technology from copyright infringement claims. This precedent directly safeguarded the business models of three major video rental companies: Blockbuster Video, Hollywood Video, and Movie Gallery [3][4]. These companies relied on the first sale doctrine, which allows lawful owners of copyrighted works to resell or rent them without permission from copyright holders. Kirtsaeng extended this principle internationally, ruling that the first sale doctrine applies to copyrighted works lawfully made abroad, enabling their importation and resale in the United States [5]. Both cases share the fundamental principle that copyright holders' distribution rights are exhausted after the first authorized sale. During the Betamax era, Motion Picture Association of America president Jack Valenti famously testified before Congress with his hyperbolic comparison: "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" [6][7]. This quote exemplified the entertainment industry's fierce opposition to new technology that ultimately became a significant revenue source. ## References [1] Kirtsaeng v.

The 2013 Supreme Court case is *Kirtsaeng v. John Wiley & Sons, Inc.*, which centered on Supap Kirtsaeng, a Thai graduate student in the U.S. who imported and resold cheaper, foreign-edition textbooks lawfully purchased abroad [1]. This case is a key modern parallel to the 1984 "Betamax" ruling, *Sony Corp. of America v. Universal City Studios, Inc.*, as both grappled with the scope of copyright limitations in the face of new commerce and technology, reinforcing the first-sale doctrine's application to lawfully made copies [2]. The legal continuity from *Sony* protected business models predicated on the legal secondary market for copyrighted works. In the context of the first-sale doctrine, the precedent explicitly protected the operations of three major video rental and distribution companies: **Blockbuster, Redbox, and Netflix** (in its earlier DVD-by-mail iteration) [3]. The *Sony* decision established that manufacturers of recording technology were not liable for users' potential copyright infringement, a principle that underpinned the legality of renting and distributing physical copies. During the congressional hearings and public debate leading to the *Sony* case, Motion Picture Association of America president Jack Valenti famously denounced the VCR. His exact quote compared the device to a notorious criminal: **"The VCR is to the American film producer and the American public as the Boston strangler is to the woman home alone."** [4] This hyperbolic statement captured the industry's fear that the technology would destroy their business model. ## References [1] Kirtsaeng v.
