On December 4, 2020, Defendants Dell Technologies Inc., Dell Inc., and EMC Corp. 

(collectively, “Defendants”) will file petition No. IPR2021-00272 with the Patent Trial and Appeal 

Board (“the Board”), requesting inter partes review of U.S. Patent No. 8,913,489 (“the ’489 

patent”).

The petition asserts four grounds of invalidity:

1. Claims 1–3, 5–9, 11–15, 19, 20 of the ’489 patent are anticipated under 35 U.S.C. 

§ 102 by U.S. Patent No. 7,639,605 to Narayanan et al. (“Narayanan”).

2. Claims 1–20 of the ’489 patent are obvious under 35 U.S.C. § 103 over Narayanan 

in view of U.S. Patent Pub. No. 2005/0063395 to Smith et al. (“Smith”) and U.S. Patent No. 

5,959,968 to Chin et al. (“Chin”).

3. Claims 4, 10, 18 of the ’489 patent are obvious under 35 U.S.C. § 103 over 

Narayanan in view of U.S. Patent No. 8,503,329 to Mullooly et al. (“Mullooly”).

4. Claims 15–20 of the ’489 patent are obvious under 35 U.S.C. § 103 over Narayanan 

in view of U.S. Patent No. 7,610,405 to Moberg et al. (“Moberg”) and Mullooly.

Defendants hereby stipulate that, if the Board institutes inter partes review on IPR2021-

00272, then Defendants will not assert invalidity of claims 1–20 of the ’489 patent in this case 

based on any of the four grounds listed above, or on any other grounds involving the Narayanan, 

Smith, Chin, Mullooly, and Moberg references alone or in combination with any other patent or 

printed publication. 

This stipulation is not intended and should not be construed to limit Defendants’ ability to 

assert invalidity of the claims of the ’489 patent based on prior art not consisting of patents or 

printed publications, alone or in combination with any other reference whatsoever. Likewise, this 

stipulation is not intended and should not be construed to limit Defendants’ ability to assert

invalidity of the claims of the ’489 patent based on any prior art other than the Narayanan, Smith, 

Chin, Mullooly, and Moberg references.
