Thank Kerensky that is over.
A plain language explanation:
There were talks, they resulted in an agreement placed before the judge of dismissal with prejudice, with no voluntary elements listed. This means that once Judge Zilly signs the documentation in its current form IT IS OVER. Harmony Gold can never come back at any of the Battletech developers, including Catalyst Games Labs and no restrictions or caveats are placed. Some monies may have changed hands indirectly, but there is no deal made or required to keep the reseen on or off the table.
I do not know how this effects the resolution of earlier legal agreements, but Harmony Gold cannot in any way come after Catalyst Games Labs, Piranha Games or Harebreained Schemes for the use of the reseen variants of the following designs:
Stinger, Wasp, Phoenix Hawk, Valkyrie, Rifleman, Archer, Warhammer, Marauder and Longbow.
Other reseen mechs such as Locust (Crusher Joe) and Shadow Hawk, Thunderbolt, Battlemaster (Dougram) amongst others were never under threat due to prior friendly agreements with the IP holders of the unseen designs.
We know that there are models made for Warhammer and Marauder for HBS Battletech computer game. The legal wording means that these can be used. Whether the Macross derivative reseen will in fact be used I cannot say, but it is now just a question of which mechs to code, not which mechs can be legally included. A business decision rather than a legal one.
There may still be terms restrictions on discussing settlements active from earlier lawsuits, I dont now if those terms are still valid, and I cannot assume that the original unseen are in any way available, those rights still belong to their respective IP holders, which may or may not include Harmony Gold.
However at current state of play the reseen are now free from legal controversy from Harmony Gold, and Harmony Gold is prohibited from going after them again.
