I have found that at least one of the patents contested (U.S. Patent No. 6,879,268, formerly filed as 10/054,610) was indeed properly declared by Nokia back in 2002 [1].

Edit: I have found other contested patents that were properly declared but I already said quits and let the courts decide on this.

Final edit: I gave up reviewing Nokia's declarations after finding matches in the filing. Apparently, the so-called contested patents (at least those that I have checked) were called differently when Nokia submitted the declaration (Lenovo's legal reviewed the patent numbers but did not looked if they matched the filing number). I have looked at some contested patents and it seems that Nokia did declare them properly as far back as 2002, so I genuinely don't know what Lenovo is trying to claim here. Accordingly, I let others complete the review here.
