Optical Effects Patents

This list of patents was collected as part of the research for my dissertation Image as Collective: A History of Optical Effects in Hollywood's Studio System (2014). It does not claim to be a comprehensive list in the sense of containing all patents that cover the field but rather gathers those that were considered to be relevant at the time. There are a few key selections here and patents, which are part of one or more of these, are marked accordingly in the collections column. The cpc column provides information on each patent's classification according to the Cooperative Patent Classification.

• StullProducersPool: W. Stull, "Producers Pool Composite Process Patents," American Cinematographer 17, no. 11 (November 1936): 461, 466–68. An article on the patent pool that lists some but not all patents, which were part of the patent pool agreement.
• WestheimerF*n*: The Margaret Herrick Library holds the Joseph and Katherine Westheimer collection of patents but the exact origin of and intention behind this collection remains unclear. Joseph Westheimer, at some time, worked for Warner Bros, one of the studios involved in the patent conflicts of the early 1930s. This suggests that the studio compiled the collection as part of its technical and legal research. On the other hand, there are hints in the papers that rather refer to Paramount. The patents are organized in folders and are listed here accordingly:
  • Folder 4: Miscellaneous patents circa 1900-1962
