06 Apr PTAB EXPERT WITNESS TESTIMONY, CONSULTING AND TRIAL TESTIFYING SERVICES
PTAB expert witness testimony providers who offer testifying during Patent Trial and Appeal Board matters provide critical technical and legal insights in proceedings that challenge validity. Leaders combine subject matter expertise with knowledge of USPTO procedures as top PTAB expert witness options to deliver informed opinions on intellectual property matters.
5 Common Types of Cases for PTAB Expert Witnesses
- Inter Partes Review (IPR) Proceedings
These cases require detailed analysis of prior art to determine if patent claims were anticipated or rendered obvious by existing technologies, publications, or products available before the patent’s priority date.
- Post-Grant Review Challenges
Top PTAB expert witnesses review recently issued patents for any statutory grounds of invalidity, including subject matter eligibility, novelty, non-obviousness, written description, and enablement requirements.
- Covered Business Method Reviews
When financial service patents are challenged, experts assess whether claimed innovations represent technological advancements or merely abstract business concepts implemented with conventional technology.
- Patent Owner Preliminary Responses
These cases involve PTAB expert witness picks analyzing petition arguments and providing technical context to defend patent validity before the board institutes a formal review proceeding.
- Derivation Proceedings
Experts evaluate evidence to determine if an inventor derived the claimed invention from another party rather than independently developing the innovation.
