Namely, the defendants were found to be infringing the plaintiff's copyrights, infringing trademark, as well as performing acts of unfair trade practices and unfair competition. The Wisconsin court order showed the defendants were ordered to pay damages to the plaintiff for the defendants' acts. In reaching the settlement, the defendants did not admit any fault or wrongdoing. The remaining details of the agreement were sealed.

PKWARE also agreed to cease any use of SEA's trademark 'ARC' and to change the names or marks used with PKWARE's programs to non-confusing designations.

In exchange, PKWARE licensed SEA to use its source code for PKWARE's ARC-compatible programs.

#PKWARE PKZIP LICENSE#

PKWARE agreed to pay SEA to obtain a license that allowed the distribution of PKWARE's ARC-compatible programs until January 31, 1989, after which PKWARE would not license, publish or distribute any ARC compatible programs or utilities that process ARC compatible files. Under the agreement, SEA licensed PKWARE for all the ARC-compatible programs published by PKWARE during the period beginning with the first release of PKXARC in late 1985 through July 31, 1988, in return for an undisclosed payment. On August 2, 1988, the plaintiff and defendants announced a settlement of the lawsuit, which included a confidential cross-license agreement. He stated that PKARC was a derivative work of ARC, pointing out that comments in both programs were often identical, including spelling errors.

The most substantial evidence at trial was from an independent software expert, John Navas, who was appointed by the court to compare the two programs. SEA sued Katz for trademark and copyright infringement. In the late 1980s, a dispute arose between System Enhancement Associates (SEA), maker of the ARC program, and PKWARE. This led to PKWARE missing out on the opportunity to be the first to bring PKZIP to the platform, with WinZip becoming the standard tool on the platform instead.

Katz was adamantly opposed to Microsoft Windows in the early 1990s. His family assisted him in running the company, but he eventually fired them when they denied him access to the company's profits. Although PKWARE became a multimillion-dollar company, Katz was more noted for his technical expertise than business prowess. PKZIP made Katz one of the most well-known shareware authors of all time. Steve Burg, a former Graysoft programmer, joined PKWARE in 1988.

(Phil Katz Software) in 1986, with the company's operations located in his home in Glendale, Wisconsin, but he remained at Graysoft until 1987. Strong positive feedback and encouragement prompted Katz to release his compression program, PKARC, and eventually to make his software shareware. Its much greater speed caused it to spread very quickly throughout the BBS community. He first publicly released only PKXARC, an extraction program, as freeware. Katz had a special flair for optimizing code: besides writing critical code in assembly language, he would write C code to perform the same task in several different ways and then examine the compiler output to see which produced the most efficient assembly code. PKARC, written partially in assembly language, was much faster. ARC was written in C, with the source code available on System Enhancement Associates' bulletin board system (BBS). At the time, he had worked on an alternative to Thom Henderson's ARC, named PKARC. Katz left Allen-Bradley in 1986 to work for Graysoft, a Milwaukee-based software company. He wrote code to run programmable logic controllers, which operated manufacturing equipment on shop floors worldwide for Allen-Bradley's customers. After his graduation, he was hired by the Allen-Bradley company as a programmer. Katz graduated from the Computer Science Engineering program at the University of WisconsinвЂ“Milwaukee. Phil Katz was a graduate of Nicolet High School in Glendale, Wisconsin.
