Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gandhi.
Regarding claim 4:
The method as claimed in claim 1, the method comprising: automatically disallowing the wireless device from joining the cluster as a worker node if the wireless device is not authorised to join the cluster; and wherein the wireless device is not authorised to join the cluster if the wireless device is not registered to an owner of the master node and the cluster of worker nodes.
As set forth in paragraph [0028], in order to accept a request for a new mobile device, the cluster master authenticates the requesting mobile device by verifying that the mobile device belongs to a contact list or requesting the user to provide a security code, or through other handshaking protocol. Therefore, the Examiner finds that it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to understand that a new mobile device would not be allowed to join the cluster if the device is not authorized/authenticated or not on the contact list (thus not registered). The Examiner notes that if the mobile device is not on a contact list then it is not registered to an owner of the mobile device.
This Examiner further finds that it would be obvious to a person of ordinary skill in the art to disallow the wireless device since Gandhi specifically discloses of providing security in both a WiFi network and the Internet communications. Thus, disallowing a device would have been predictable to a person of ordinary skill in the art based on Gandhi teaching of authenticating the requesting devices and only allowing devices which have been authenticated.
Claim(s) 7, 9, 10, 39 and 42 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gandhi in view of Wang et al. US Patent Pub. 2020/0366474.
Regarding claims 7 and 39:
Claim 7: The method as claimed in claim 1, wherein: the wireless device is authorised to join the cluster if the wireless device has a public key that corresponds to a private key of the master node.
Claim 39: The method as claimed in claim 35, wherein: the wireless device is authorised to join the cluster if the wireless device has a public key that corresponds to a private key of the master node.
Gandhi does not specifically disclose of authorization based on whether the wireless device has a public key that corresponds to a private key of the master node.
Nonetheless, Wang discloses in paragraph [0317] that each terminal has its own public/private key pair. Wang explains that a private key is based on a user ID and a master private key. In paragraph [0027], Wang explains that the public key is of the second terminal (see also paragraph [0031]). In paragraph [0034], the first terminal is the master node and the second terminal is the slave node.
Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to use public and private keys as disclosed by Wang. The Examiner notes that Gandhi discloses of the importance of authenticating the devices as well as providing a more secure authentication. See paragraph [0028] of Gandhi which discloses that other methods can be used. Wang, which is also directed to having a terminal send a join request to a master terminal, disclose of providing a secure communication in which private/public keys are exchanged. As explain in paragraph [0664], this would improve a trust degree and security of the network elements in the group. Wang explains that private keys can prevent communication information between groups from being stolen. See paragraph [0255].
Regarding claim 9:
The method as claimed in claim 7, the method comprising: acquiring the private key from a memory of the master node; and
Wang in paragraph [0569] discloses that the shared key (includes private key) is stored in the first terminal (i.e. master device). See also paragraph [0612]. See also paragraph [01229] which explains that the first terminal includes a memory.
acquiring the private key from a node that is separate from the master node and worker nodes.
Wang discloses that the private key can be acquired from an IKMS entity which is separate from the master and slave devices. See paragraphs [0019 and 0086-0089].
As set forth above, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Gandhi by including private/public keys for security reasons.
Regarding claims 10 and 42:
Claim 10: The method as claimed in claim 9, wherein: acquiring the private key from the node that is separate from the master node and worker nodes comprises: initiating transmission of a request for the private key towards the node that is separate from the master node and worker nodes; and receiving a response from the node that is separate from the master node and worker nodes, wherein the response comprises the private key.
Claim 42: The method as claimed in claim 35, the method comprising: initiating transmission of a request for the public key towards the entity; and receiving the public key from the entity in response to the request.
As set forth in paragraph [0317], Wang discloses the private key of the terminal is generated by a private key generation center (KGC) (node that is separate from the master node and worker nodes). As explained in paragraph [0319], a terminal can apply to the KGC for a private key and the KGC generated the private key for the terminal.
As set forth above, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Gandhi by including private/public keys for security reasons.
Claim(s) 8 and 40 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gandhi in view of Wang and further in view of Matson et al. US Patent Pub. 2014/01372418.
Regarding claims 8 and 40:
Claim 8: The method as claimed in claim 7, wherein one or both: one or both of the public key and the private key are set by the owner of the one or both of the master node and the cluster of worker nodes; and one or both of the public key and the private key are modifiable by the owner of the one or both of the master node and the cluster of worker nodes.
Claim 40: The method as claimed in claim 39, wherein one or both: one or both of the public key and the private key are set by the owner of the one or both of the master node and the cluster of worker nodes; and one or both of the public key and the private key are modifiable by the owner of the one or both of the master node and the cluster of worker nodes.
As set forth above, Gandhi in view of Wang discloses the use of both public and private keys. In addition, Wang discloses that the private keys are based on the email addresses or telephone numbers (see paragraph [0317] and thus are set by the owner of either the master (first terminal) or worker (second/slave terminal). The Examiner notes that since addresses may change, it would have been obvious to a person of ordinary skill in the art that the public/private keys can be modifiable by the owners of the devices.
Nonetheless, to the extent it is considered that the keys are not modifiable, the Examiner finds that it would have been obvious to a person of ordinary skill in the art to have the keys modifiable by the owner of the device.
As explained by Matson it was known to generate new public/private key pairs and to discard old private/public key pairs. See paragraph [0046]. The Examiner notes that Matson explains that using old credentials can lead to being denied access to data (see paragraph [0002]). As explained in paragraph [0046], credentials can be set to expire and thus, by allowing public/private keys to be modifiable, this would enhance security.
Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the private/public keys. The Examiner finds that Gandhi in combination with Wang both disclose of providing a secure communication and exchange of data as well as the use of private/public keys. In addition, Matson likewise discloses that it was known to modify private/public keys in order to ensure that the credentials are updated frequently in order to provide old credentials from being used. The Examiner finds that a person of ordinary skill in the art would understand that this would lead to increase security between the terminals since it will allow the keys to be frequently updated and changed.

Primary Examiner, Art Unit 3992
1 The Examiner maintains that the claims recite contingent limitations. In accordance with MPEP 2111.04 which recites, “The broadest reasonable interpretation of a method (or process) claim having contingent limitations requires only those steps that must be performed and does not include steps that are not required to be performed because the condition(s) precedent are not met.” The Examiner notes that claim 1 includes two “if statements” and therefore, if the wireless device is not authorized, then the limitations set forth in the claim need not be performed. In addition, the Examiner finds that each of the method claims 1, 3, 4, 6, 7, 35, 37, and 39 recite contingent limitations. In addition as per claims 33 and 60, see MPEP 2111.04 with respect to contingent limitations.
