Case Histories – Patent Infringement

  • Signa showed that a number of downhole tool patents were infringed upon, and that a person of ordinary skill in the art (POSITA) would have understood the relevant technology in the accused’s submitted patents was infringing upon that technology.
  • Our team demonstrated the true inventor of an air drilling process after a patent was issued for that technique.
  • Signa’s team of engineers and graphics specialists reviewed several multilateral drilling processes to determine if a patent had been infringed upon. Extensive application studies were conducted with an economist on economic projections (10-year span) to demonstrate the monetary setback suffered by the patent holder.
  • Signa engineers answered technical questions in a patent case involving the use of numerous patented well-treatment services. Signa analyzed well treatment service records to determine the patent had been infringed upon.
