Prior art

To identify the most relevant prior art for US patent 6958986, I will examine the patent citations listed within the patent document itself. The USPTO provides tools to search for patent information, including citations.

Since I cannot directly access the USPTO database for live search results in this environment, I will rely on the provided patent text to identify the cited prior art. The patent text typically includes a "References Cited" section that lists relevant patents and publications.

After identifying the cited patents, I will then extract the requested information for each reference: full citation, publication/filing date, a brief description (based on the patent's own characterization if available, or a general understanding of the reference's relevance to the patented invention), and which claim(s) of US6958986 it potentially anticipates under 35 U.S.C. § 102.

Based on the provided patent text for US6958986, the following prior art is explicitly mentioned:

Most Relevant Prior Art for US Patent 6958986

1. Pritchett '807 patent

• Full Citation: The provided text refers to "the Pritchett '807 patent" without a full patent number. Assuming this is a US patent, the full citation format would typically be US X,XXX,807. Without the full patent number, a precise publication/filing date or direct link to the patent is not available from the provided text alone.
• Publication/Filing Date: Not explicitly stated in the provided text for "the Pritchett '807 patent."
• Brief Description: This patent "discloses the acquisition, by a fixed initiating wireless communication system from a fixed receiving wireless communication system, of a list of the wireless communication systems operating in the network and a corresponding respective time slot list for each wireless communication system. A table is then created based upon the list for scheduling time slots among the wireless communication systems."
• Potential Anticipation (35 U.S.C. § 102): The Pritchett '807 patent describes a system for scheduling time slots in a network of fixed wireless communication systems. US6958986, in its broadest sense, concerns wireless communication systems with enhanced time slot allocation. The key distinguishing feature highlighted in US6958986 is the application to mobile communication systems and the use of directional antennas, which are described as being complex to schedule (e.g., "Scheduling time slots for wireless communication systems operating with directional antennas, particularly when the wireless communication systems are mobile, is complex."). Therefore, Pritchett '807 would likely anticipate aspects of US6958986 related to general time slot scheduling and network topology discovery in wireless systems, but not those specifically tied to mobility, directional antennas, or dynamic interference avoidance/mitigation inherent in the claims of US6958986. For example, claims related to determining relative positions of mobile nodes and potential interference to directional links (e.g., as generally described in the "Another communication method aspect of the invention" where a controller determines relative positions of a neighboring mobile node and potentially interfering mobile nodes for scheduling a directional link if interference is below a threshold) would likely not be anticipated by Pritchett '807 due to its focus on fixed systems. However, any claim broadly covering the concept of creating a list of wireless communication systems and their time slots for scheduling could potentially be anticipated. Without specific claims of US6958986 to analyze against the full text of Pritchett '807, a definitive determination is difficult.

To conduct a more thorough analysis of potential anticipation, the full text of the Pritchett '807 patent and the specific claims of US6958986 would be required. Given the information, the focus of US6958986 on mobility and directional antennas with associated interference management and dynamic allocation strategies appears to be a key differentiation from the described Pritchett '807 patent.
