Verdicts and Settlements:

  • Klein & Wilson represented the chief financial officer (CFO) of an international corporation that abruptly terminated the CFO in violation of his employment agreement. Before filing a lawsuit, Klein & Wilson negotiated a $2.8 million settlement for the CFO, which far exceeded the mandated severance package in the employment agreement., 2015
  • Klein & Wilson won a verdict of $1.4 million in a breach of implied contract and copyright infringement case against one of the largest retailers in the United States. The jury awarded every penny Klein & Wilson requested. The Court commented that Klein & Wilson's multimedia trial presentation was the best it had ever seen., 2004
  • Klein & Wilson won a verdict of $2.25 million in a premises liability action stemming from a sexual assault of a tenant of a residential apartment complex. This was one of the largest verdicts of its kind in California., 2000
  • Klein & Wilson won a verdict of approximately $5 million on behalf of one of its software clients against Siemens Business Communications, Inc., one of the largest companies in the world. Affinitec prevailed on all of its breach of contract claims and recovered 99 percent (99%) of all the damages it requested from the jury. Siemens filed a cross-complaint against Klein & Wilson's client, but recovered nothing., 1999
  • In a construction defect case, Klein & Wilson represented a homeowners' association consisting of 48 condominium units. The developers and contractors denied there were construction defects and refused to pay anything. After conducting a "show-and-tell" presentation of the defects at the project and inviting all the defendants to destructive testing, the defendants recognized they would be found liable and paid Klein & Wilson's client approximately $1.5 million.
  • Klein & Wilson represented a City against its former City Attorney for legal malpractice arising out of the City Attorney's failure to identify and resolve a conflict of interest. The conflict of interest sparked negative media attention, a public audit, and a criminal prosecution. Ultimately, the City was forced to reimburse funds spent on a public project. When Klein & Wilson substituted into the case, the former City Attorney refused to offer a penny to resolve the case. After Klein & Wilson evaluated the case and presented the former City Attorney with facts showing it had substantial exposure at trial, Klein & Wilson was successful in resolving the case for $1.5 million without taking a single deposition.
  • Klein & Wilson represented a company which hired design professionals and a general contractor to construct a sales facility in Central California. The designers and contractors made a number of errors, resulting in construction defects. Because of insurance coverage issues, the defendants' insurance carriers refused to settle until Klein & Wilson took approximately 50 depositions and proved that each defendant had serious exposure. After several mediations, Klein & Wilson recovered $3 million for its client - enough money for the client to make the necessary repairs to its facility.
