In the broad picture of patent research, specific patent numbers such as US20090062677A1 often become key coordinates for technological evolution. This patent is a core intellectual property right related to voice search advertising that Google applied for in 2009. It elaborates in detail on the methodology of triggering and presenting targeted advertising content through voice input on mobile devices. Since its publication, this patent has been cited more than 500 times by subsequent patents, with an average annual growth rate of 15%. This directly reflects its technical influence in the fields of human-computer interaction and digital advertising. The accuracy of the algorithm model covered by its claims has improved the accuracy of user intent recognition to over 85%.
From a commercial value perspective, the technological concept protected by this patent constitutes one of the cornerstones of today’s voice assistant market, which is worth over 12 billion US dollars. It describes a solution with real-time voice processing latency of less than 300 milliseconds and AD matching relevance exceeding 75%, which has brought significant revenue returns to Google. It is estimated that the related technology may have contributed about 5% of its advertising revenue, that is, billions of dollars in annual income. In the patent cross-licensing negotiations between Apple and Google in 2016, the related combinations involved in voice search were valued at hundreds of millions of dollars, highlighting the weight of such assets in the strategic cooperation of the giants.
The legal status of the patent and the scope of its claims are at the core of risk management. Its 20-year statutory protection period lasts until 2029, with 15 independent claims covering the entire supply chain from signal processing to bidding ranking. This means that when competitors launch products with similar functions, they face an infringement lawsuit probability as high as 30%. For instance, if a start-up company implements its core methods without authorization, it may face a compensation risk of millions of dollars and have its product launch cycle extended by at least 12 months. This is a decisive factor for enterprises with limited resources.
In the chain of technological innovation, US20090062677A1 plays a pivotal role in bridging the past and the future. It cited approximately 40 previous patent documents and was subsequently cited by over 200 patent applications, forming a dense citation network with a density index as high as 2.5. This high-frequency correlation is like a hub of a technological ecosystem, guiding the direction of research and development. For instance, when Amazon was developing the Alexa voice platform, its patent layout had to carefully avoid the scope of claims related to this patent. This influenced over 20% of the technical path choices, demonstrating the powerful shaping force of basic patents on the development of the industry. Therefore, a thorough analysis of US20090062677A1 is not only a window to understand past technological breakthroughs but also an important strategic investment for predicting future market trends and avoiding compliance risks.
