Analysis of Infringement of U.S. Patent No. 7,216,301 by Microchip Technology Incorporated

Plaintiffs Caddo Systems, Inc. and 511 Technologies, Inc. (“Caddo”), provide this final and exemplary infringement analysis 

with respect infringement of U.S. Patent No. 7,216,301, entitled “ACTIVE PATH MENU NAVIGATION SYSTEM” (the “’301 

patent”) by Microchip Technology Incorporated (“Microchip”). The following chart illustrates an exemplary analysis regarding 

infringement by Microchip’s products and services (“’301 Accused Instrumentalities”):

(i) web pages and content, including user interfaces such as a hierarchical information structure, to be interactively presented 

in browsers, including, without limitation, the web pages and content accessible via https://www.microchip.com/ (as shown 

below) including www.microchipdirect.com and maintained on servers located in and/or accessible from the United States 

under the control of Defendant that allow navigating a multi-level hierarchical information structure, where each level in 

the information structure contains plural items, each item being at least one of a function, a pointer to a location, and a 

pointer to another level; 

(ii) software, including, without limitation, software that allows web pages and content to be interactively presented in and/or 

served to browsers to facilitate navigating within a multi-level hierarchical information structure, where each level in the 

information structure contains plural items, each item being at least one of a function, a pointer to a location, and a pointer 

to another level; and

(iii) computer equipment, including, without limitation, computer equipment that stores, serves, hosts, supports, and/or runs any 

of the foregoing or that allows navigating within a multi-level hierarchical information structure, where each level in the 

information structure contains plural items, each item being at least one of a function, a pointer to a location, and a pointer 

to another level, and any products, devices, systems, and/or components of systems with the same or substantially the same 

technical features and/or functionalities.

 

The analysis set forth below is based largely upon information from publicly available resources regarding the Accused 

Instrumentalities and Microchip’s limited discovery production, as discovery in this matter has not yet been completed. 

Unless otherwise noted, Caddo contends that Microchip directly infringes the ’301 patent in violation of 35 U.S.C. § 271(a) by 

making, using, and/or selling, and/or offering to sell in the United States, and/or importing into the United States, without authority or 

license, the Accused Instrumentalities.

Plaintiffs’ Final Infringement Contentions 

Civil Action No.: 6:20-cv-245

Claim Chart re: U.S. Patent No. 7,216,301

2

The following exemplary analysis demonstrates that infringement. Unless otherwise noted, Caddo further contends that the 

evidence below supports a finding of indirect infringement under 35 U.S.C. § 271(b) and 35 U.S.C. § 271(c) in conjunction with other 

evidence of liability.

Unless otherwise noted, Caddo believes and contends that each element of each claim asserted herein is literally met through 

Microchip’s provision or importation of the Accused Instrumentalities. However, to the extent that Microchip attempts to allege that 

any asserted claim element is not literally met, Caddo believes and contends that such elements are met under the doctrine of 

equivalents. More specifically, in its investigation and analysis of the Accused Instrumentalities, Caddo did not identify any 

substantial differences between the elements of the patent claims and the corresponding features of the Accused Instrumentalities, as 

set forth herein. In each instance, the identified feature of the Accused Instrumentalities performs at least substantially the same 

function in substantially the same way to achieve substantially the same result as the corresponding claim element.

Caddo reserves the right to supplement and/or amend the positions taken in this infringement analysis, including with respect

to literal infringement and infringement under the doctrine of equivalents, if and when warranted by further information obtained by 

Caddo, including but not limited to information adduced through information exchanges between the parties, fact discovery, expert 

discovery, and/or further analysis.

The ’301 Accused Instrumentalities dynamically construct an Active Path, which has been construed by this Court (Dkt. 34) as a 

sequence of links dynamically created as a menu item is navigated, as a sequence of active links as items are selected using the 

graphical user menu system, with one said active link corresponding to each of the items selected, said active links providing direct 

access to one of a function, corresponding level and menu item without the need to navigate using said graphical user menu system.

For example, the ’301 Accused Instrumentalities dynamically construct a sequence of links dynamically created as a menu item is 

navigated, as the sequence of active links as items are selected (e.g., the ’301 Accused Instrumentalities dynamically construct a 

sequence of links dynamically created (e.g., “Amplifiers and Linear—Comparators”) as the sequence of active links as items are 

selected (e.g., as “Amplifiers and Linear” and “Comparators” are selected)), with one said active link corresponding to each of the 

items selected. Said active links provide direct access to one of a function, corresponding level and menu item without the need to 

navigate using said graphical user menu system (e.g., the ’301 Accused Instrumentalities’ sequence of links dynamically created as a 

menu item is navigated “Amplifiers and Linear—Comparators” corresponds to each of the items sequentially selected, including 

“Amplifiers and Linear” and “Comparators”).

short-cut is 

executed, 

with one said 

active link 

corresponding 

to each of the 

items 

necessary to 

access said 

given item 

using said 

graphical user 

menu system.

The ’301 Accused Instrumentalities dynamically construct the Active Path, which has been construed by this Court (Dkt. 34) as a 

sequence of links dynamically created as the menu system is navigated, when a pre-defined short-cut is executed, with one said active 

link corresponding to each of the menu items necessary to access said given menu item using said graphical user menu system.

For example, the ’301 Accused Instrumentalities dynamically construct the sequence of links dynamically created as the menu system 

is navigated when a pre-defined short-cut is executed, with one said active link corresponding to each of the menu items necessary to 

access said given menu item using said graphical user menu system (e.g., the sequence of links dynamically created as a menu item is 

navigated is automatically constructed when “Amplifiers and Linear” or “Comparators” is executed, with each active link “Amplifiers 

and Linear” or “Comparators” corresponding to each of the menu items necessary to access the given menu item using the graphical 

user menu system).

3. The method 

for navigating

rolling over a 

selected 

active link 

triggers the 

display of 

sibling items 

on the 

hierarchically 

subordinate 

levels 

associated 

with said 

selected 

active link.

The ’301 Accused Instrumentalities roll over a selected active link to trigger the display of sibling items on the hierarchically 

subordinate levels associated with said selected active link.

For example, for the ’301 Accused Instrumentalities, rolling over a selected active link triggers the display of sibling items on the 

hierarchically subordinate levels associated with said selected active link (e.g., the ’301 Accused Instrumentalities allow rolling over 

the link “Amplifiers and Linear” to trigger the display of sibling items on the hierarchically subordinate levels associated with the 

selected active link “Amplifiers and Linear” such as “Operational Amplifiers,” “Instrumentation Amplifiers,” “Current Sense 

Amplifiers,” “Comparators,” “Programmable Gain Amplifiers,” and “DC Power Current Monitors”) as shown below:

See, e.g., https://www.microchip.com/design-centers/amplifiers-linear/comparators (last visited Feb. 10, 2020).

Claim Chart re: U.S. Patent No. 7,216,301

38

As another example, in the ’301 Accused Instrumentalities, rolling over a selected active link triggers the display of sibling items on 

the hierarchically subordinate levels associated with said selected active link (e.g., rolling over and selecting “Microcontrollers and 

Microprocessors” in “Products / Microcontrollers and Microprocessors / 8-bit MCUs”) to trigger the display of sibling menu items on 

the hierarchically subordinate levels (e.g., “Product Categories,” “Developments,” “Software Solutions,” “Application Design 

Centers,” and “Product Selections”), as shown below:

See https://www.microchip.com/en-us/products/microcontrollers-and-microprocessors (last accessed Jun. 8, 2021).

To the extent Microchip contends that the ’301 Accused Instrumentalities do not literally meet the limitation of “rolling over a selected 

active link triggers the display of sibling items on the hierarchically subordinate levels associated with said selected active link,” the 

limitation is met under the doctrine of equivalents by the ’301 Accused Instrumentalities because they perform substantially the same

each said 

active link 

enabling the 

user to 

directly 

browse all 

items on any 

given level of 

the 

hierarchical 

information 

structure 

including all 

hierarchically 

subordinate 

items without 

affecting the 

Active Path.

Each said active link in the ’301 Accused Instrumentalities enables user to directly browse all items on any given level of the 

hierarchical information structure including all hierarchically subordinate items without affecting the Active Path, which has been 

construed by this Court (Dkt. 34) as a sequence of links dynamically created as a menu item is navigated.

For example, each active link in the ’301 Accused Instrumentalities enables the user to directly browse all items on any given level of 

the hierarchical information structure including all hierarchically subordinate items without affecting the sequence of links

dynamically created as a menu item is navigated (e.g., the ’301 Accused Instrumentalities enable the user to directly browse all items 

under “Amplifiers and Linear” such as “Operational Amplifiers,” “Instrumentation Amplifiers,” “Current Sense Amplifiers,” 

“Comparators,” “Programmable Gain Amplifiers,” and “DC Power Current Monitors” without affecting the sequence of links 

dynamically created as a menu item “Amplifiers and Linear—Comparators”) as shown below:

under “Automotive Solutions” such as “Automotive Products,” including all hierarchically subordinate items such as 

“Microcontrollers,” “Analog Products,” “Connectivity,” “Automotive Touch,” “Car Access,” “memory Products,” “High Temperature

Products,” “Timing Solutions,” and “Automotive Security” without affecting the sequence of links (e.g., without affecting the links in 

“Home / Automotive Solutions / Automotive Applications”) dynamically created as a menu item is navigated) as shown below:

For example, the user can directly browse all items on any given level of the hierarchical information structure including all 

hierarchically subordinate items in the path “Products / Microcontrollers and Microprocessors” such as “Product Categories,” 

“Development Tools,” “Software Solutions,” “Application Design Centers,” and “Product Selections” without affecting the path 

“Products / Microcontrollers and Microprocessors” (e.g., the user can browse items under “Product Categories,” “Development 

Tools,” “Software Solutions,” “Application Design Centers,” or “Product Selections” without affecting the path “Products / 

Microcontrollers and Microprocessors.”).

As another example, each active link in the ’301 Accused Instrumentalities enables the user to directly browse all items on any given
