3. Motivation
MPEG-2 patents are a logical reference point for IPR analysis for royalty-free MPEG Internet Video Codec
MPEG-2 patent pool scrutinized by US Department of Justice*
Pool list updated regularly since 1996
MPEG-2 is widely deployed (digital TV, DVDs, Blu-ray, etc.)
MPEG-2 is a core competency of MPEG/WG11
By July 2013, anticipated completion of MPEG IVC standard:
75% of (US) patents will have expired
25% of (US) patents will remain
11% (15 patents) outside interlace & systems categories will remain
* See US Department of Justice Business Review Letter, MPEG LA, L.L.C., et al., June 26, 1997, at

“Emergence of Essential Patents in Technical Standards: Implications of the Continuation and Divisional Application Systems and the Written Description”**
"With regard to the MPEG-2 standard, % are those based on divisional, continuation, or CIP applications."
Nero AG v. MPEG LA
“Because at least two patents in the original [1996] pool will not expire until 2014, it is impossible that the [subsequently added] patents were added to extend the duration of the MPEG-2 pool because the “new” patents expire before the original patents.”*** *

Continuation: "a second application for the same invention claimed in a prior nonprovisional application and filed before the original prior application becomes abandoned or patented.... The disclosure presented in the continuation must be the same as that of the original application; i.e., the continuation should not include anything which would constitute new matter if inserted in the original application." MPEP
Continuation-in-part: "an application filed during the lifetime of an earlier nonprovisional application, repeating some substantial portion or all of the earlier nonprovisional application and adding matter not disclosed in the said earlier nonprovisional application." MPEP
Divisional: "A later application for an independent or distinct invention, carved out of a pending application and disclosing and claiming only subject matter disclosed in the earlier or parent application .... A divisional application is often filed as a result of a restriction requirement made by the examiner." MPEP
Patent Cooperation Treaty (PCT): provides a mechanism by which an applicant can file a single application that, when certain requirements have been fulfilled, is equivalent to a regular national filing in each designated Contracting State. "[T]he applicant has up to 18 months more than he has in a procedure outside the PCT to reflect on the desirability of seeking protection in foreign countries ...." WIPO, Patent Cooperation Treaty
Foreign filed application: "Under certain conditions and on fulfilling certain requirements, an application for patent filed in the United States may be entitled to the benefit of the filing date of a prior application filed in a foreign country, to overcome an intervening reference or for similar purposes." MPEP "Foreign priority ... is not considered in determining the term of a patent." MPEP 2701.
