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

"With regard to the MPEG-2 standard, ... 44% are those based on divisional,
continuation, or CIP applications."
“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.”***

Glossary
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 201.07
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 201.08
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 201.06
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 201.13. "Foreign priority ... is not considered in determining the term of a
patent." MPEP 2701.
