About Sidespin Group

In software litigation, the biggest challenge isn’t finding an expert with technical credentials—it’s finding one who can actually explain complex technology to a judge or jury, and hold up under cross-examination.

Sidespin Group exists to solve that problem. Founded in 2019 by Dr. Istvan Jonyer, a PhD computer scientist with experience building systems at Nortel, launching products at Google, and evaluating technology at venture capital firms, Sidespin Group assembled a curated network of 20+ testifying experts. Each one combines rigorous academic credentials with senior industry experience and demonstrated courtroom communication skills.

Every engagement reflects a single standard: technical rigor, clear communication, and opinions that hold up under pressure.

We adopted the name Sidespin Group to honor his legacy and to remind us to be game-changing at whatever we do.

What’s in a name?

In table tennis, the sidespin loop is a shot that curves the ball in unexpected ways—so effective that when our founder’s father, 4-time world champion Istvan Jonyer Sr., used it, the rules of the game were changed.

We named our firm Sidespin Group to honor that legacy. In software litigation, conventional analysis often misses what matters. We find the angles others overlook. We deliver technical opinions with the precision and clarity that changes the trajectory of a case.
