US 9146925

US Patent 9146925, titled "User defined internet jukebox kiosks set top box," was issued on September 29, 2015, from an application filed on July 27, 2010. The sole inventor is Manuel Ignacio Tijerino, and the current assignee is listed as "Individual".

Abstract:
The patent describes a computer-readable storage method and system that allows artists to upload media (images, video, and music) to a server. This media is then made available in a system of internet jukeboxes located in various establishments for instant playback by paying customers. The system is programmed to maintain an account for the artist, enabling them to earn fees and royalties from media playback. It also provides for automated payment of rent and other fees to the establishment, service provider, and licensing agencies.

Independent Claims Overview:

• Independent Claim 1: This claim outlines a computer-implemented method for real-time music distribution of new media, allowing an artist to control its availability for playback in public venues via a jukebox. Key steps include providing user interfaces for enrollment, account creation, login, and media upload. The system receives the new media, automatically identifies and stores its metadata (including a mathematically manipulated Root Mean Square (RMS) value for audio normalization) in a database, and stores the media in a central storage device. This process instantly makes the media available for jukebox playback over the internet through API calls. Upon request, the system streams the media to the jukebox, calculates earnings for the artist and venue, and receives payment indications. The claim emphasizes that audio signals of the new media are normalized by applying gain based on the obtained RMS value and further compressed using a preset ratio and threshold.
• Independent Claim 3: This claim describes a non-transitory computer-readable medium embodying program instructions that, when executed by a computer, perform a method similar to Claim 1. The instructions adapt the computer for real-time music distribution of new media, allowing an artist to control its availability for playback in public venues via a jukebox. The steps encompass providing user interfaces for authoring, user addition, account creation, login, and media upload. The program instructions handle receiving new media, automatically identifying and storing its metadata (including the mathematically manipulated RMS value) in a database, and storing the media in a central storage device. This enables the jukebox to request and play the media over the internet. The instructions further cover streaming the requested media, calculating artist and venue earnings, and receiving payment indications. Similar to Claim 1, the claim specifies that audio signals are normalized by applying gain based on the RMS value and compressed using a preset ratio and threshold.

Proceedings overview

There is one AIA trial proceeding on US Patent 9146925, which is currently in the "Trial Instituted" status. This means the patent's validity is actively being challenged, and no claims have been definitively invalidated or sustained yet. A defendant's posture is therefore pending the outcome of this ongoing IPR.

IPR2025-01280 — Spotify AB et al. v. Manuel Ignacio Tijerino

• Type: Inter Partes Review
• Filed: 2025-07-11
• Status: Trial Instituted (meaning the PTAB has decided to review the patentability of the challenged claims)
• Judge panel: Not publicly available at this stage in the proceedings.
• Petition grounds: Not publicly available in the provided snippet. Typically, IPR petitions challenge claims under 35 U.S.C. §§ 102 (novelty) and/or 103 (obviousness) based on prior art patents and publications.
• Institution decision: Instituted. The exact date of institution is not provided, but the status "Trial Instituted" confirms it has occurred. The reasoning would have been that Spotify AB et al. demonstrated a reasonable likelihood that at least one challenged claim is unpatentable.
• Final Written Decision (if issued): Not yet issued, as the proceeding is still in the "Trial Instituted" phase.
• Settlement / termination: Not settled or terminated.
• Appeal: Not applicable, as a Final Written Decision has not been issued.
• Defensive value: This active IPR means that the patentability of the challenged claims is currently under scrutiny. The outcome will significantly impact any assertion of this patent. If claims are invalidated, it weakens the patent owner's position. If claims are sustained, it strengthens the patent's presumption of validity against the grounds raised.

Strategic summary

Currently, no claims of US Patent 9146925 are definitively CANCELED or SUSTAINED through AIA trial proceedings. All claims remain UNTESTED by a Final Written Decision. The patent is presently undergoing examination in IPR2025-01280. Therefore, the patent has not yet been narrowed through IPR.

Regarding the estoppel landscape, if IPR2025-01280 proceeds to a Final Written Decision, Spotify AB et al. (and their privies) would be estopped under 35 U.S.C. § 315(e)(2) from asserting in future district court litigation or other USPTO proceedings any ground of unpatentability that they raised or reasonably could have raised during this IPR. For other potential defendants, prior-art grounds not raised or that could not have been reasonably raised by Spotify AB et al. in this IPR would still be available.

There is no discernible pattern of multiple IPRs filed by the same petitioner or aggressive PTAB appeals by the patent owner at this time, as only one IPR is on file and it is still pending.

Recommended next steps

Since IPR2025-01280 is currently in the "Trial Instituted" phase, the key upcoming milestone is the Final Written Decision, which is typically due one year from the institution date. Monitoring the progress of IPR2025-01280 through the USPTO PTAB E2E system is crucial to understand which claims, if any, are ultimately found unpatentable.

Inventors

Manuel Ignacio Tijerino is the sole inventor. The patent does not specify his employer at the time of filing; however, the original and current assignee is listed as "Individual", suggesting he was self-employed or acting independently at the time of filing.

Original assignee

The original assignee is listed as "Individual" (Manuel Ignacio Tijerino). It is unclear from the patent text whether the inventor, as an individual, shipped a product embodying the claims directly. The patent describes a system to allow artists to upload media to a server and have it available on internet jukeboxes, implying a service rather than a physical product. His primary line of business, based on the patent, appears to be related to providing this media distribution and monetization platform for artists. His current status (operating, acquired, dissolved, in bankruptcy) is not determinable from the patent document itself.

The explicit detailing of the audio mastering process applied to newly uploaded artist content in a jukebox context is a strong distinguishing feature of claims 1 and 3.

Obviousness Analysis of US Patent 9146925 Under 35 U.S.C. § 103

This analysis identifies combinations of prior art references that would render the claims of US Patent 9146925 obvious to a person having ordinary skill in the art (PHOSITA) at the time of the invention (priority date: May 4, 2007). A PHOSITA in this field would possess a background in networked media systems, digital signal processing for audio, and/or interactive entertainment systems (e.g., jukeboxes), familiar with web technologies, database management, network protocols, audio processing, and basic audio engineering.

The core of the claims (e.g., Independent Claims 1 and 3) describes a system for artists to upload media to a central server, which then becomes instantly available for playback on networked jukeboxes in public venues. The system further includes automatic metadata identification, real-time audio mastering (normalization and compression), and automated calculation and distribution of earnings to artists and venues.

Obviousness Combination 1: Networked Digital Jukebox with User-Uploaded Content, Metadata Management, and Automated Payments

This combination addresses the fundamental architecture of the claimed invention, including artist interaction, media distribution, and financial aspects.

Motivation for Combination and How Claims are Met:

A PHOSITA would have been motivated to combine these references to create a more dynamic and inclusive digital jukebox system. The problem addressed by US9146925 is the difficulty local artists face in getting their music played on traditional jukeboxes. By combining a networked digital jukebox system (Guy, Davis) with a personal digital content management system that allows user uploads (Loudeye), a PHOSITA would foresee the benefit of enabling any artist to easily submit their media to the jukebox network. This would broaden content availability and enhance user engagement.

• User Interfaces and Media Upload (Claim 1: "providing... a user interface to add the user... to create an account... to log into... to add the new media to the system"; "receiving... the new media"): Loudeye teaches user interfaces for uploading and managing personal digital content. Applying such known online content management interfaces to a jukebox content system (Guy, Davis) would be an obvious design choice for allowing artists to self-publish their media.
• Metadata Identification and Storage (Claim 1: "automatically identifying... metadata for the new media and storing the metadata in a database"): Nilsson provides a well-known standard for audio file metadata. A PHOSITA integrating a digital media system would obviously include functionality to automatically extract and store such metadata in a database for efficient search and retrieval, as commonly done in any digital content management system.
• Central Storage and Instant Availability (Claim 1: "storing... the new media in a central storage device, wherein the storing automatically enables the new media to be requested by the jukebox for playback over the Internet by providing to a client software installed in the jukebox, access to the database storing the metadata for the new media, via an API call over the Internet"): Davis teaches automatic media updates for digital jukeboxes, implying a central storage accessible over a network. The concept of networked clients accessing server-side data (metadata and media) via API calls over the Internet for "instant availability" is a fundamental aspect of online content distribution, as shown in prior art like US6519648B1 ("Streaming media search and continuous playback of multiple media resources located on a network").
• Automated Earnings and Payments (Claim 1: "automatically calculating... amounts earned by an artist and a venue...; and receiving... indication of payment"): Digital jukeboxes inherently involve payments for plays. Guy mentions "revenue-enhancing features" in a jukebox context. Given the prevalence of online payment systems (Shopnow.Com) and the desire to manage royalties efficiently in a system designed for artist self-promotion, automating the calculation and distribution of earnings to artists and venues would be an obvious business process improvement for a PHOSITA.

Obviousness Combination 2: Incorporating Real-Time Audio Mastering Techniques

This combination specifically addresses the audio signal processing steps recited in the claims.

References:

1. Combination 1 (Guy, Davis, Loudeye, Nilsson, Shopnow.Com) - provides the foundation of the user-uploadable networked jukebox system.
2. General knowledge in audio engineering and signal processing: By the 2007 priority date, techniques such as Root Mean Square (RMS) analysis for measuring audio loudness, applying gain for volume normalization, dynamic range compression with preset ratios/thresholds, and hard limiting were well-established audio engineering practices.

Motivation for Combination and How Claims are Met:

The problem of inconsistent audio levels and dynamic range from diverse, user-uploaded content played on a public sound system (like a jukebox) was a known issue to a PHOSITA. Such inconsistencies could lead to jarring listening experiences or even damage venue speaker systems. The motivation for a PHOSITA to combine the networked jukebox system (from Combination 1) with known audio processing techniques would be to ensure a consistent and high-quality listening experience for customers and protect venue equipment, thereby enhancing the commercial viability and user satisfaction of the system. The patent itself identifies this problem, stating that other jukeboxes "turn artists away for this exact reason," while the present invention "helps artists by mastering their track on the fly."

• Audio Signal Analysis and Metadata Storage (Claim 1: "automatically analyzing... audio signals... for determining a root mean square (RMS) value, wherein the RMS value is further mathematically manipulated for obtaining a positive RMS value less than 1; storing... the obtained RMS value less than 1 as metadata"): RMS analysis is a standard method for determining the average loudness of an audio signal. Mathematically manipulating this value (e.g., scaling it to be less than 1) to derive a suitable gain factor for normalization is an obvious design choice for a PHOSITA. Storing such derived audio properties as metadata (following the principles of Nilsson for metadata management) for later use in playback is a logical extension.
• Real-Time Audio Normalization and Compression (Claim 1: "the audio signals... are normalized... by applying gain to the signals based on the obtained positive RMS value less than 1, and wherein, the audio signals... are further compressed for reducing a dynamic range of the signal based on a preset compression ratio and a preset threshold value"): Applying gain based on an RMS-derived value for normalization, followed by dynamic range compression and limiting, are standard audio mastering techniques. In a streaming media context (as in the networked jukebox from Combination 1), applying these techniques "on the fly" (as described in the patent) during streaming rather than through pre-processing would be an obvious implementation choice for a PHOSITA to ensure instant availability and efficient use of resources. This would involve known digital signal processing methods applied to the audio stream as it is played.

Therefore, the combination of a networked digital jukebox system capable of receiving user-uploaded content with automated metadata and payment processing (Combination 1), and the application of well-known real-time audio mastering techniques (RMS analysis, gain, dynamic range compression, hard limiting) to ensure consistent playback quality, would have been obvious to a PHOSITA at the time of the invention, driven by motivations to broaden content, improve user experience, and streamline business operations.

PTEs are typically granted to compensate for delays incurred in obtaining regulatory approval for patented products, primarily for pharmaceuticals, medical devices, and food additives. Given the nature of this patent, which relates to an internet jukebox system, it is unlikely to qualify for a PTE.

Continuation Applications

US9146925 (Application number US12/804,665) claims priority from US11/744,228, which was published as US20080275942A1, titled "User Defined Internet Jukebox Kiosks Set Top Box". This indicates that US9146925 is a continuation-in-part or continuation of US11/744,228. The patent text explicitly lists US11/744,228 as a "Related Parent Application" and US9146925B2 as "Applications Claiming Priority" from US11/744,228.

Divisional Applications

The provided patent text does not explicitly list any divisional applications directly originating from US9146925. Divisional applications are filed when a patent application contains claims to more than one independent and distinct invention, and the USPTO requires restriction.

Related Family Members

The patent text identifies the following related family members:

• US11/744,228: This is the priority application from which US9146925 claims priority. It was published as US20080275942A1, also titled "User Defined Internet Jukebox Kiosks Set Top Box".
• US20110029417A1: This is listed as another version of the patent, suggesting it is a related publication (e.g., a published application corresponding to the granted patent US9146925B2).

Projected Expiration Date

The "Legal status" section of US9146925 on Google Patents explicitly states the "Anticipated expiration" date as 2030-07-27.

This date is typically calculated as 20 years from the earliest priority filing date, plus any granted Patent Term Adjustments (PTA), minus any disclaimed patent term (e.g., due to a terminal disclaimer). The filing date of the application leading to US9146925 was July 27, 2010. However, it claims priority from an earlier application (US11/744,228) with a priority date of May 4, 2007. The 20-year term from the earliest priority date (2007-05-04) would normally expire around 2027-05-04. The anticipated expiration date of 2030-07-27 suggests that a Patent Term Adjustment of approximately 3 years and 2 months was granted for USPTO delays during prosecution.
