In a 2000 episode of "Martial Law" titled "Dog Day Afternoon," one has a bad guy patent attorney and a bad guy patent backer/investor.
The story unfolds with the shooting death of a man, whose body was found by Sammo and friends, underneath a howling dog.
After uncovering a patent application buried in the ground (with the help of the dog), Sammo interviews the relevant patent attorney, who does not remember the patent application of victim/inventor Mason Talbot but does remember that Talbot was fired by Caltech because Talbot had the attention span of a tsetse fly, moving from one invention to another. In fact, the patent attorney remembered this invention very well.
In particular, in the case of this literally "buried" invention, Talbot had reduced the invention to practice, re-wiring the nerves of a dog "Homer," who went from not able to walk to fully functioning dog. The patent attorney, without contacting Talbot, went to investor Zelliger, but the inventor Talbot refused to deal, because he considered Zelliger evil. The patent attorney himself then cut a deal with Zelliger, arguing he could get any resultant patent invalidated.
As shown in the opening, the evil Zelliger himself shot and killed Talbot and later, with henchman, spent a large part of the episode trying to capture Homer, presumably to take the dog apart to understand the "working" embodiment of the invention.
The patent attorney finally confesses his evil actions, and Sammo and friends arrive just in time to save Homer. Homer goes after Zelliger in the resultant fight scene.
There is some interesting dialog from the patent attorney about inventors who do not grasp the business side of things. We have an extreme result here, wherein the investor both kills the inventor and tries to steal the idea. Sammo recognizes that the inventor had given up his life to save the dog (and the invention).
The "feel good" ending here has the NIH being given all the relevant information.
The patent attorney "Carrington" is played by David Wells.
