Abstract
Abstract Described is a mechanism for dependably synchronizing data element activities on web pages among a group of browsers. The web browsers retrieve web pages from an HTTP server. Each of the web pages contains at least one data element and embeds a Master Applet and at least one DTS Applet (DTS stands for data tracking and synchronization). In response the data element activities (such as entering data into a data field) performed at a browser, the DTS Applet passes the activities to the Master Applet, which in turn reports the activities (together with the URL of the web page on which the data element activities have occurred) to a tracking server. The tracking server sends the activity report (together with the URL of the web page on which the data element activities have occurred) to the Master Applets at all participant browsers. The participant Master Applets then instruct their respective DTS Applets to display the data element activities on the web page identified by the URL.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
84 words
A method of synchronizing data elements between a first terminal and a second terminal, the data elements in data fields on pages retrieved from a server, comprising the steps of: (a) at the first terminal, loading and displaying a first page from the server, the first page including at least one data element; (b) at the first terminal, entering or changing data elements in the data field; and (c) at the first terminal, sending the entered or changed data elements to the second terminal.
Claim 2
Independent Claim
84 words
A method of synchronizing data elements between a first terminal and a second terminal, the data elements in data fields on pages retrieved from a server, comprising the steps of: (a) at the first terminal, loading and displaying a first page from the server, the first page including at least one data element; (b) at the first terminal, entering or changing data elements in the data field; and (c) at the first terminal, sending the entered or changed data elements to the second terminal.
Claim 3
Dependent Claim
105 words
The method of claim 1, further comprising the steps of: (d) at the first terminal, loading and displaying a second page, the second page containing location information for indicating a location of the loaded program, the second page including a least one data field; and (e) at the first terminal, executing the loaded program based on the location information in the second page; (f) at the first terminal, entering data elements into the data field of the second page; and (g) at the first terminal, the program sending entered or changed data elements of the data field in the second page to the second terminal.
Claim 4
Dependent Claim
35 words
A method of claim 1, comprising associating the first page with a page locator for indicating a location of the first page in the page server; and sending the page locator to the second terminal.
Claim 5
Dependent Claim
40 words
The method of claim 3, comprising sending the entered or changed data elements on the first page to a data synchronization server and then relaying the entered or changed data elements from the data synchronization server to the second terminal.
Claim 6
Dependent Claim
17 words
The method of claim 3, the page locator being URL, and the location information being a tag.
Claim 7
Dependent Claim
59 words
The method of claim 3, further comprising the step of: at the second terminal, loading the first page; at the second terminal, displaying the first page including the data field on the first page; and at the second terminal, displaying the entered or changed data elements in the data field on the first page displayed on the second terminal.
Claim 8
Dependent Claim
12 words
The method of claim 1, the page server being an HTTP server.
Claim 9
Dependent Claim
29 words
The method of claim 1, comprising locating information included in the first page indicating a location of a program and, at the first terminal, loading and executing the program.
Claim 10
Dependent Claim
12 words
The method of claim 8, wherein the program is a Java applet.
Claim 11
Dependent Claim
24 words
The method of claim 1, comprising loading and executing, at the first terminal, a master applet, a DTS applet and a session ID applet.
Claim 12
Independent Claim
87 words
A method of synchronizing data elements between a first terminal and a plurality of other terminals, the data elements in data fields on pages retrieved from a server comprising the steps of: (a) at the first terminal, loading and displaying a page from a page server, the page including at least one data element; and (b) at the first terminal, entering or changing data field elements in the data field; and (c) at the first terminal, sending the entered or changed data elements to the other terminals.
Claim 13
Independent Claim
87 words
A method of synchronizing data elements between a first terminal and a plurality of other terminals, the data elements in data fields on pages retrieved from a server comprising the steps of: (a) at the first terminal, loading and displaying a page from a page server, the page including at least one data element; and (b) at the first terminal, entering or changing data field elements in the data field; and (c) at the first terminal, sending the entered or changed data elements to the other terminals.
Claim 14
Dependent Claim
