An experienced IP attorney can provide expert testimony on the procedural aspects of obtaining patents, obtaining trademarks and obtaining copyrights without encroaching on the province of the Court or the jury.  No matter how well you understand what the government did, and why, your explanation and presentation to the Court is "argument" when what you need is evidence.

          Unfortunately there are situations where the client believes that counsel has committed malpractice.  Once again, an experienced IP attorney can provide testimony not only on the procedural aspects of obtaining IP protection, but also testimony on the manner in which litigation was handled.
