== Patent litigation ==

=== Electronic marker patents ===

Smart Parts became involved in extensive patent litigation concerning electropneumatic paintball marker technology.

The company's patent portfolio included inventions associated with the original Shocker, particularly the electronic control of pneumatic loading and firing mechanisms.

United States Patent 6,035,843, granted on 14 March 2000, identified David Smith, Raymond Gaston, Bill Gardner and Adam Gardner as inventors.

The patent concerned a pneumatically operated projectile-launching device incorporating electronic controls.[13]

Smart Parts subsequently pursued patent infringement claims against several paintball manufacturers.

=== Indian Creek Designs ===

In November 2002, Smart Parts commenced patent infringement proceedings against [[Indian Creek Designs]] (ICD) in the United States District Court for the District of Oregon.

The litigation concerned electronic marker technology covered by Smart Parts' patents.

In September 2003, the companies announced a settlement.

Under the agreement, Indian Creek Designs agreed to make an undisclosed payment and to manufacture electronic markers covered by the disputed technology under licence from Smart Parts.[14]

The settlement followed a partial summary judgment concerning infringement of United States Patent 6,474,326.

=== WDP litigation ===

Smart Parts also pursued patent infringement proceedings against British manufacturer [[WDP]], producer of the Angel marker.

The dispute concerned United States Patent 6,474,326 and the ownership of inventions associated with electronically controlled paintball markers.

WDP challenged the patent's inventorship, arguing that engineer Dr Edward Hensel had contributed to the invention but had not been named as an inventor.

On 23 August 2004, the United States District Court for the District of Oregon granted WDP's motion for summary judgment on inventorship.

The court determined that Hensel was a joint inventor and rejected Smart Parts' arguments that his rights had been assigned to PneuVentures or were otherwise unavailable to WDP.[15]

The ruling concerned the inventorship and ownership of the specific patent involved in the dispute. It did not invalidate every Smart Parts patent or establish that all electronic paintball markers were free from patent restrictions.

=== Industry response ===

Smart Parts' patent enforcement activities became controversial within the paintball industry.

Manufacturers and players debated the breadth of the patents, the legitimacy of the company's claims and the effects of licensing requirements on competing manufacturers.

The founders subsequently defended their actions, arguing that patent enforcement was necessary to protect investments in research and development.[1]

The litigation affected licensing relationships and the manufacture of electronic markers during the 2000s.
