I think this'll round off my Ken Penders coverage for now -- maybe I'll post more when there's news; maybe I'll write a post about why I care enough about the rights to silly mid-1990's Sonic the Hedgehog comics to spend so much time and so many words on the subject, just as soon as I figure that out myself.
Anyway, here's a list of articles about Archie v Penders and the related legal disputes. I posted comments in many of these threads myself, and it's interesting (to me at least) to watch as I go from initial skepticism -- "Penders signed a contract, he had to have" -- to eventually realizing that the root of Penders's claim is that no, he didn't sign a contract, and then slowly come to believe that he's right and Archie really did forget to make him sign one.
Far and away the most legwork on this story has been done by Tristan Oliver of TSSZ News. TSSZ's coverage has been extensive, and I intend to link a few highlights here; please understand that this is by no means an exhaustive sample of everything Oliver and his associates have written on the subject. For a more thorough list, check their Penders+Copyright tag.
By the way, though: I would advise not reading the comments section on any TSSZ News story about the Penders case. The comments section is a wretched hive of scum and villainy.
(Also: My sister-in-law owns cats named "Tristan" and "Oliver". That's kinda weird.)
Ken Penders Presents... by Ken Penders, kenpenders.com, 2010-07-07. Ken's opening salvo, where he first claims that he owns or co-owns the copyrights to everything he ever wrote or drew for Archie's Sonic the Hedgehog, Knuckles the Echidna, and assorted related specials.
Has Archie Lost Rights to Sonic Reprints? by Johanna Draper Carlson, at her blog Comics Worth Reading, 2010-07-11, mirrored on archive.org. This is the first I heard of the story; Ken's name was a bit of a blast from the past and I was surprised to hear it in the comics news.

Archie v Penders thread at Brontoforumus, 2010-07-12 to present -- this thread is assembled from all the posts I (and others, but mostly I) have written on the subject for the past several years across multiple threads. It makes for a good quick run-down to read it all end-to-end.
Archie Comics Files Federal Lawsuit Against Ken Penders, by Tristan Oliver, TSSZ News, 2010-12-01. While there had been legal wrangling prior to this, this is where the lawsuits actually started. And it is important to remember, throughout this discussion, that while fanboys continue to misstate the basic facts of the case, Archie sued Ken Penders, not the other way around. (Penders has sued Sega and EA -- we'll get to that in a bit -- but he has not sued Archie. Archie sued him.)
Penders Affidavit Offers Intimate Look At His Sonic Comics Tenure by Tristan Oliver, TSSZ News, 2011-03-03. Oliver looks over the affidavit. This is where the meat of the dispute starts to become clear: Penders is claiming he never signed a work-for-hire agreement; Archie has submitted documentation to the contrary but Penders is disputing its authenticity; Penders has other creators from the same period who back up his story. Money quote: "First, the signatures are not believed by me to be authentic."

Ken Penders Files Lawsuit Against Sega, Electronic Arts by Tristan Oliver, TSSZ News, 2011-06-01. As the name implies, this is the filing of Penders v Sega and EA, over the game Sonic Chronicles: The Dark Brotherhood, which features characters who resemble the Dark Legion from Ken's Knuckles comics.
Inside Ken Penders’s Copyright Lawsuit Against Sega, EA by Tristan Oliver, TSSZ News, 2011-06-03. More detail on the suit, notably including Penders's allegations that BioWare approached him about helping develop Sonic Chronicles, which would certainly imply they were familiar with his work and the Dark Brotherhood's resemblance to the Dark Legion is not coincidental.
The Ken Penders/Archie Comics Lawsuit Continues by Rich Johnston, Bleeding Cool, 2011-06-24. More coverage of the contracts Archie submitted as an exhibit in the case, and Penders's claim -- with support from Scott Shaw and Elliot S Maggin -- that the contracts are illegitimate.
Coming Soon in 2012, by Ken Penders, kenpenders.com, 2011-12-01; Ken's statement of intent to publish his characters in his own comics, without Archie or Sega (or Sega's trademarks). At the time of this writing the thread has posts in it on up through last October; a lot of it is just Ken going in circles patiently trying to explain copyright and trademark law to his forum trolls, but if you can get through it there's a lot of edifying information on the claims he's making in the case and the legal tack he's taking with them.
Ken Penders To Publish Sonic The Hedgehog Characters On His Own by Rich Johnston, Bleeding Cool, 2011-12-04; a response to the above post. The comments thread has some interesting discussion and links related to how Archie handled the TMNT license; the TMNT Adventures comic ended around the same time the Sonic comic started.
Inside the Archie v. Penders Pre-Trial Report by Tristan Oliver, TSSZ News, 2012-02-13. Notes some of the names on the witness list; a number of former Archie editors and freelancers were slated to testify and corroborate Ken's claim that Archie did not make him or other Sonic freelancers sign work-for-hire agreements.

Ken Penders Stops Diamond From Distributing Sonic Collections by Rich Johnston, Bleeding Cool, 2012-09-14. This was an early sign that Penders's claims were causing trouble for Archie; in the months since Archie has continued to put out reprints of Penders's Sonic work through Diamond, but among other measures it's altered covers so that his characters don't appear on them.
Settlement Terms Reached in Archie v. Penders Copyright Case by Tristan Oliver, TSSZ News, 2012-12-04. For a minute there, it really looked like it was almost over.
Flynn Addresses Altered Sonic #244; Fans Look To Penders Settlement by Tristan Oliver, 2012-12-27. A recent issue of Sonic the Hedgehog has most of the Knuckles the Echidna supporting cast sent through a Warp Ring and effectively written out of the series indefinitely. Notably, the characters in question are among those Penders created and is seeking to claim copyright on.
Archie Fighting Proposed Dismissal of Penders Copyright Case by Tristan Oliver, TSSZ News, 2013-03-27. And then the talks broke down and Penders moved for dismissal. In one of my favorite legal filings ever, Archie's lawyer argues against dismissing the case with prejudice because this would be, and I quote, "greatly prejudicial".
Penders Counsel Asks Court to Ban Knuckles Archives #4 Sale, Related Material in Dispute by Tristan Oliver, 2013-04-19. Ken's tightening the screws and pushing for an injunction; the judge has not made a decision yet.
Archie Desperate To Settle, But Can’t Without Sega – The Latest In The Ken Penders Sonic Comics Case by Rich Johnston, Bleeding Cool, 2013-05-09. A fantastic transcript of a May 2 court session; the judge quotes Laurel and Hardy but the transcript reads more like an Abbott and Costello routine. Counsel for both Archie and Penders state that they want to settle but that they haven't been able to get Sega to sign off on their terms.
And here we stand -- there's been no news since. The judge granted both parties more time to bring Sega to the table to approve their settlement, and that's the last we heard; neither Bleeding Cool nor TSSZ News has posted any updates on the case since.
I suspect all sides are hoping to settle rather than go to trial. If they settle, most of the terms will be private. But if talks break down, the case will go to trial. And from there, probably an appeal by whichever side loses. This could stretch on for years more. But like I said yesterday, I hope it doesn't -- I hope it gets settled on terms that are favorable to Ken.
Of course, while that would close the book on Penders's case, it wouldn't preclude all the other Sonic freelancers from that era from coming forward with claims of their own. As we've seen, there are lots of creators making the same claims Ken has -- and if he gets a settlement, they'll be angling for settlements of their own.
Update 2013-07-09: Archie v Penders has been settled. Two more related links:

Judge Officially Dismisses Archie v. Penders Case by Tristan Oliver, 2013-07-02. TSSZ News confirms that the case has been settled and the suit dismissed.
Update 2015-09-24: I'm late on this, but I recently found out that Penders v Sega et al was dismissed (due to a mistake in how the paperwork was filed, not due to any decision on the merits of the case itself).
TheAmazingSallyHogan has the most thorough summary of both cases that I have seen to date; it is well worth reading in its entirety.
