I sometimes forget that people aren't working with even a basic understanding of IP.
That's not nearly as bad as people working without an understanding of the most basic fact of all in this equation. What am I talking about? Well...
But we do see that Accolade's employees (namely P&F)
Stop. Right there. Just stop. They weren't employees of Accolade. You could've figured that out from reading the recitals in Paul's original 1988 licensing agreement with Accolade:
Publisher is in the business of developing and publishing computer software programs. Developer is in the business of developing recreational computer software programs, and desires Publisher's expertise and assistance in marketing Developer's products.
-- Licensing Agreement between Accolade, Inc. and Paul Reiche III, October 7, 1988
and later in Section 12.6 where both parties expressly characterize their relationship as involving that of Independent Contractors:
Developer will be deemed to have the status of an independent contractor, and nothing in this Agreement will be deemed to place the parties in the relationship of employer-employee...
-- Licensing Agreement between Accolade, Inc. and Paul Reiche III, October 7, 1988
Also, please note: While there is a presumption of authorship on the part of employers for the works of their employees, the same is not true of independent contractors when it comes to software. Unless you have an agreement specifying the transfer of intellectual property rights from the contractor to the contractee, all rights to said work remain with the contractor.
Short version: a game company automatically owns the game copyright, without the need for any registration or contract.
Registration is requisite in order to sue for damages in federal court. However, that's not at all what the recent registration was about. The work in question was already registered, but rather what was recently recorded was a transfer of rights over all audiovisual and textual materials (i.e. everything other than the source code) from the several authors responsible to Paul and Fred, i.e. registration# PA0002107340 which transfers "by written agreement" the rights of the listed authors to the listed copyright claimants. This is intended to undercut the argument by StarDock that this was some kind of joint work and/or that Paul & Fred were employees of Accolade rather than independent contractors (this being a claim StarDock has made in an attempt to ensure that their purchase of the Star Control trademark and its backing assets would include Star Control 2).
Stardock is trying to use these new release agreements to say that the employees owned copyrights until a few months ago (really unlikely).
Were they employees of Paul & Fred, or were they themselves independent contractors? I have a feeling the answer is "we didn't document anything very well", hence the necessity of this assignment (which they didn't have to do and was very nice of them, I might add). That, however, doesn't change anything as far as what rights StarDock has: if they were employees of Paul & Fred then Paul & Fred own it all per the terms of their licensing agreement, and if not then they owned everything severally and Accolade had no legal right to any of the audiovisual or textual assets used.
TL;DR You're wrong on some points, and if I come off sounding like a dick it's only because your post could cause confusion to the detriment of Dogar and Kazon, so apologies in advance.
