Extensions

For US Patent 5704012, the following details are available from the patent document and Google Patents data:

• Patent Term Adjustments (PTA): There is no information provided in the patent text or on the Google Patents page regarding Patent Term Adjustments (PTA). PTA calculations, as they are commonly understood today, were introduced after the Uruguay Round Agreements Act (URAA) in 1995 and became effective with the American Inventors Protection Act (AIPA) in 1999. Given the patent's issuance in 1997 and its lapse in 2002, PTA would not be a significant factor.
• Patent Term Extensions (PTE): There is no information provided in the patent text or on the Google Patents page regarding Patent Term Extensions (PTE). PTE typically applies to patents covering products subject to regulatory review periods, which is not applicable to this patent's subject matter.
• Continuation Applications: The patent document states, "The present application is related to commonly assigned copending U.S. patent application Ser. No. 08/134,764, filed Oct. 8, 1993, to Bigus, entitled "Adaptive Job Scheduling Using Neural Network Priority Functions"". While this is a related application, the current patent, US5704012 (application number US08/454,977), is not explicitly identified as a continuation of it.
• Divisional Applications: US Patent 5704012 is a divisional application. The patent text explicitly states, "This is a divisional of application Ser. No. 08/134,953 filed on Oct. 8, 1993, abandoned".

  • US08/134,764: A commonly assigned copending U.S. patent application, filed on October 8, 1993, titled "Adaptive Job Scheduling Using Neural Network Priority Functions".
