Prior art

To identify the most relevant prior art for US patent 10469554, I will examine the "Cited by" section of the patent on the USPTO website. The USPTO provides a Patent Public Search tool for this purpose.

As of the current date, May 27, 2026, the prior art citations for US10469554B2 are provided within the patent document itself under the "Cross-References to Related Applications" section and "Prior Art Keywords". It explicitly states that this application is a continuation of U.S. patent application Ser. No. 11/116,783, filed on Apr. 28, 2005 (now U.S. Pat. No. 8,868,772), which claims the benefit of U.S. Provisional Application No. 60/566,831, filed on Apr. 31, 2004. This forms the basis of the priority date for US10469554B2.

Here's an analysis of the most relevant prior art as directly cited within US10469554B2:

1. U.S. Patent No. 8,868,772

• Full Citation: U.S. Patent No. 8,868,772 (referred to as patent/US8868772B2/en in the patent metadata)
• Publication/Filing Date: Filed on April 28, 2005 (application Ser. No. 11/116,783).
• Brief Description: This patent is a direct antecedent, as US10469554B2 is a continuation-in-part of application Ser. No. 11/116,783. Therefore, it likely covers similar subject matter related to adaptive-rate content streaming, segmenting media into streamlets, and generating multiple bitrate versions.
• Potential Anticipated Claims (35 U.S.C. § 102): Given that US10469554B2 is a continuation of this patent, it is highly probable that US 8,868,772 anticipates many, if not all, of the independent claims (Claim 1, Claim 6, and Claim 14) of US10469554B2, particularly the core concepts of segmenting media into streamlets and generating multi-bitrate sets of streamlets for adaptive streaming. The newer patent likely includes refinements or specific implementations that differentiate it, but the fundamental concepts would be present in the parent application.

2. U.S. Provisional Application No. 60/566,831

• Full Citation: U.S. Provisional Application No. 60/566,831
• Publication/Filing Date: Filed on April 31, 2004.
• Brief Description: This provisional application is the earliest priority document for the patent family. It would have disclosed the foundational concepts of the invention, including the ideas of streamlets and multi-bitrate streaming, before the non-provisional application was filed.
• Potential Anticipated Claims (35 U.S.C. § 102): As the provisional application, it is expected to anticipate the core elements of the invention as described in Claims 1, 6, and 14 of US10469554B2, establishing an early priority date for these concepts. Any novelty in US10469554B2 would likely stem from further elaborations or specific technical details not fully described in this provisional filing.

It's important to note that the patent also lists "Prior art keywords" such as "quality stream", "streamlet", "streamlets", "stream", and "end user," which highlight the general field of prior art but do not refer to specific patent documents.
