Increasingly, courts have to decide whether intangible items—computer software, website algorithms, and the like—are “products” for purposes of strict liability. Counsel confronted with this question may want to start with the Second and Third Restatements of Torts. Section 402A of the Second Restatement views “products” as “chattels” or “articles.” Restatement §402A, comments a, d-e. A “chattel” is a “physical object” and “product” as “tangible personal property.” Black’s Law Dictionary, at 251, 1245 (rev. 8th ed. 2004).
The Products Liability chapter of the Third Restatement of Torts explicitly limits the definition of “product” to physical things. Section 19 of the Third Restatement defines a “product” as “tangible personal property distributed commercially for use or consumption,” with a couple of exceptions: electricity and certain forms of real property. However, courts “have, appropriately refused to impose strict product liability” where a plaintiff complains of “the information, not [of] the tangible medium.” Id. §19, comment d. The most influential decision on this point is Winter v. G.P. Putnam’s Sons, 938 F.2d 1033, 1034-36 (9th Cir. 1991)
