The user is asking for the most relevant prior art for US patent 9622032. I need to:

1. Search the USPTO database for patent 9622032 to confirm its existence and details.
2. Identify all cited prior art within the US9622032 patent document.
3. For each prior art reference, provide:
   • Full citation.
   • Publication/filing date.
   • Brief description (preferably from the patent's own description of the prior art).
   • Which claim(s) it potentially anticipates under 35 U.S.C. § 102.

From the provided patent text, I already have mentions of two specific prior art documents: US20020094801 and WO 00/27152. The patent text itself gives brief descriptions and discusses their deficiencies in relation to the claimed invention, which will be helpful for determining anticipation. I will prioritize the patent's own description of the prior art.

I will start by re-confirming the patent on USPTO (though the provided text seems authoritative) and then focusing on the explicit prior art discussed in the "BACKGROUND ART" and "DISCLOSURE OF THE INVENTION" sections, as these are the ones the patent itself identifies as most relevant for establishing novelty.## Most Relevant Prior Art for US Patent 9622032

As of April 26, 2026, the following prior art documents are identified as most relevant based on the discussion within US Patent 9622032 itself. The patent specifically contrasts its invention with these references to highlight its novelty and advantages.

1. US20020094801 (Published Patent Application)

• Full Citation: US20020094801 A1 (Published on 2002-07-18)
  • Note: The patent document refers to it as "published patent application No. US20020094801". A search confirms the publication date.
• Publication/Filing Date: Publication date: 2002-07-18. Original filing date for this publication was 2001-01-16.
• Brief Description: This document describes a technical solution where a fixed station transmits an encoded first signal, and the coverage of this signal defines a special area. The fixed station and a mobile station within this area are linked via the signal code. To prevent abuse, an embodiment suggests equipping the fixed station with receiving and comparison means for an access code, which is applied to the fixed station via the mobile station to activate the fixed station.
• Potential Anticipation (35 U.S.C. § 102): US20020094801 generally anticipates a method for monitoring a mobile station's presence in a special area using a defining signal from a device and linking it via a code. However, US9622032 argues its invention improves upon this by not requiring activation codes to be sent to or stored in the radio communication defining device, making it "easier with this present invention to realize protection against abuse of the system". Therefore, while it shares conceptual elements, US9622032 implicitly claims novelty over US20020094801 in the method of association and security, specifically by transmitting checking data to the mobile station rather than requiring the fixed station to process access codes from mobile stations.
  • The core novelty of US9622032, as stated in claim 1, lies in transmitting "checking data" to the mobile station, which the mobile station then uses to determine if a received signal is a distinctive defining signal. US20020094801's approach of sending an access code to the fixed station for its operation is a key distinguishing feature. Thus, US20020094801 does not appear to directly anticipate claim 1's characterization clause regarding transmitting checking data to the mobile station.

2. WO 00/27152 (International Application)

• Full Citation: WO 00/27152 A1 (Published on 2000-05-11)
  • Note: The patent document refers to it as "the international application WO 00/27152". A search confirms the publication date.
• Publication/Filing Date: Publication date: 2000-05-11. International filing date: 1999-10-29. Priority date: 1998-11-04.
• Brief Description: This application proposes a solution for locating a mobile station using a "guide unit" that broadcasts a short-range radio signal defining a "home area". The short-range radio signal contains the identity code of the mobile station, which the mobile station identifies as its own to notify a mobile switching center of its presence in the home area. This "home message" can then be used for defining call prices/services.
• Potential Anticipation (35 U.S.C. § 102): WO 00/27152 broadly anticipates the concept of a mobile station detecting its presence in a defined area to influence services/tariffs. However, US9622032 explicitly states that WO 00/27152 requires the "guide unit to know the identity of the mobile station". This creates a lack of flexibility, as the mobile network cannot add new special areas for a mobile station without modifying the guide units broadcasting in those areas. US9622032 claims to overcome this by allowing the transmission of "checking data" to the mobile station without modifying the radio communication defining device itself, thus making it suitable for environments with a high number of different mobile stations (e.g., airports, business centers) where storing all mobile station identity codes in a single defining device would be difficult or impossible due to limited radio spectrum.
  • Claim 1 of US9622032 specifies that the "same checking data being sent to any mobile station whose presence in this special area is monitored". This contrasts with WO 00/27152 where the signal "contains the identity code of said mobile station that has to identify its own identity code". This is a key distinguishing feature, as WO 00/27152's guide unit needs specific mobile station identities, while US9622032's defining device does not, relying instead on generic "checking data" known to the mobile station.## Most Relevant Prior Art for US Patent 9622032

As of April 26, 2026, based on the discussions within US Patent 9622032, two prior art documents are identified as most relevant to understanding the patent's scope and novelty. The patent specifically addresses limitations found in these references to establish its inventive step.

1. US20020094801 (Published Patent Application)

• Full Citation: US20020094801 A1
• Publication/Filing Date: Published July 18, 2002. The underlying application was filed on January 16, 2001.
• Brief Description: This document discloses a system where a fixed station transmits an encoded signal that defines a special area. A mobile station within this area is linked to the fixed station via the signal code. To prevent system abuse, one embodiment proposes providing the fixed station with receiving and comparison means for an access code, which the mobile station applies to activate the fixed station.
• Potential Anticipation (35 U.S.C. § 102): US20020094801 generally anticipates a method for monitoring a mobile station's presence in a special area using a defining signal. However, US9622032 distinguishes itself by transmitting "checking data" to the mobile station for use in determining a distinctive signal, rather than requiring the fixed station to receive and compare access codes from the mobile station to become operational. This difference, as highlighted in US9622032, offers easier protection against system abuse by centralizing the management of checking data on the network side and within the mobile station, without needing to configure the radio communication defining device with specific activation codes for each mobile station. Therefore, US20020094801 does not appear to directly anticipate the characterization of claim 1 of US9622032, which focuses on the transmission of checking data to the mobile station.

2. WO 00/27152 (International Application)

• Full Citation: WO 00/27152 A1
• Publication/Filing Date: Published May 11, 2000. The international application was filed on March 27, 2007, claiming priority to an earlier European Patent Application.
• Brief Description: This international application describes a solution for locating a mobile station using a "guide unit" that broadcasts a short-range radio signal to define a "home area." The short-range radio signal contains the identity code of the mobile station, which the mobile station uses to identify itself and notify a mobile switching center of its presence in the home area. This notification can then be used to define prices or services for telephone calls.
• Potential Anticipation (35 U.S.C. § 102): WO 00/27152 presents a system for location-based service adaptation. US9622032, however, states that this prior art requires the "guide unit" to know the identity of each mobile station, which limits flexibility. This is particularly problematic for environments with a high number of different mobile stations (e.g., airports or business centers) because storing and transmitting all mobile station identity codes from a single radio communication defining device would be difficult or impossible due to limited radio spectrum. US9622032's invention addresses this by providing "checking data" to the mobile station, allowing the mobile station to determine its presence in a special area without requiring the radio communication defining device to store individual mobile station identities. Claim 1 of US9622032 specifies that the "same checking data is sent to any mobile station whose presence in this special area is monitored," directly contrasting with WO 00/27152's approach of sending individual identity codes to specific mobile stations.
