Exercise 2: Why "Old Character" Doesn't Mean "Fully Public Domain" — Possible Solution ==================================================================== THE OVERSIMPLIFICATION BEING MADE ------------------------------ Treating "this character is old" as equivalent to "everything about this character is public domain" assumes a character and everything ever written about it enters the public domain as one single, unified block, all at once. That assumption ignores that a long-running character can appear across many separate works published at very different times, each with its own, separately calculated copyright term. THE SPECIFIC MECHANISM THIS CHAPTER DESCRIBES ------------------------------ Per this chapter, most Sherlock Holmes stories fell into the public domain decades ago on their own individual terms, while "a handful of his very last stories, published in the 1920s, remained separately protected for years afterward under their own, later term." Each story is its own distinct copyrighted work with its own publication date and its own expiration point - the character himself isn't a single work with one uniform copyright status, he's a recurring element across dozens of individually-dated works. WHAT THE KLINGER CASE CONFIRMED ------------------------------ Per this chapter, the 2014 Klinger v. Conan Doyle Estate case established that "character traits and story elements that only first appeared in those still-protected final stories could not be freely used" even while the character overall, and the bulk of the stories, were long since public domain. This means the safe, correct question isn't "is this character old enough to be public domain?" but "which specific work did this particular detail, trait, or story element first appear in, and has THAT specific work's own term expired?" WHY THIS MATTERS BEYOND JUST SHERLOCK HOLMES ------------------------------ Any character or work spanning many years of publication can have this same fragmented status - early installments in the public domain, later ones still protected, with the dividing line falling exactly at whichever specific story or detail is being used, not at some single, overall "is this character old" judgment. WHY THIS WORKS AS AN ANSWER ------------------------------ It names the exact flawed assumption being made (character = one uniform copyright status), explains the mechanism this chapter actually describes (each work has its own separately calculated term), and applies the real court case's own finding to explain why even a specific trait or detail's origin matters, not just the character's general age.
