Indep. 

Cl.

1-P

A device for 

generating power 

during a locomotion 

cycle from mechanical 

energy of a living 

body, the device 

comprising an energy 

absorbing and 

converting device 

configured to be 

disposed across a joint 

of the living body,

To the extent the preamble is limiting, Bionic Power Inc. (“Defendant”) makes, uses, sells, and/or offers others to sell a

device for generating power during a locomotion cycle from mechanical energy of a living body, the device comprising an 

energy absorbing and converting device configured to be disposed across a joint of the living body

This element is infringed literally, or in the alternative, under the doctrine of equivalents.

For example, Defendant provides Amplify which is an augmented exoskeleton (“device”) for human legs. The exoskeleton 

comprises components including but not limited to a motor/generator (“energy absorbing and converting device”), gait 

sensors, and a microprocessor. When a user straps the Amplify exoskeleton to his leg (“across the joint”) and begins 

walking ("locomotion cycle"), the sensors detect the user's gait and the motor/generator transforms the kinetic energy (due 

to leg movement) (“mechanical energy of a living body”) into electrical energy. The electrical energy produced is then 

stored in a battery.

Furthermore, human walking exhibits a locomotion cycle in two phases i.e., a stance phase and a swing phase. During 

the stance phase, the limb is placed on the ground to propel the human body in a forwarding direction. In the swing phase, 

the limb is flexed to leave the ground and brought forward to commence the movement.

1-a the energy absorbing 

and converting device 

configured to be 

selectively in an 

engaged state and in 

a disengaged state 

during selected 

portions of the 

locomotion cycle while 

the energy absorbing 

and converting device 

remains disposed 

across the joint of the

living body;

Defendant provides the energy absorbing and converting device configured to be selectively in an engaged state and in a 

disengaged state during selected portions of the locomotion cycle while the energy absorbing and converting device 

remains disposed across the joint of the living body.

This element is infringed literally, or in the alternative, under the doctrine of equivalents.

For example, Defendant provides Amplify augmented exoskeleton that comprises components including but not limited to 

a motor/generator (“an energy absorbing and converting device”), gait sensors, and a microprocessor. The exoskeleton 

is designed to be attached to the user’s leg (“across a joint of a living body”). When a user straps the Amplify exoskeleton 

to his leg and begins walking ("locomotion cycle"), the exoskeleton engages and disengages in two phases (“selectively 

in an engaged state and in a disengaged state”) i.e., stance phase and swing phase. In the stance phase (“an engaged 

state”), the motor/generator in the exoskeleton absorbs the kinetic energy and converts it into electrical energy when the 

breaking is performed by the joint muscles to decelerate the joint movement.

Upon information and belief, since the exoskeleton absorbs and augments energy in the stance phase, it is obvious that 

during the swing phase (“a disengaged state”) the knee muscles do not absorb the energy or help the exoskeleton to 

generate energy.

1-b wherein the device is 

engaged to absorb 

mechanical energy of 

the living body only 

during a portion of the 

locomotion cycle 

during which muscles 

of the joint would 

otherwise be doing 

work across the joint 

to absorb mechanical 

energy of the living 

body,

Defendant provides a device wherein the device is engaged to absorb mechanical energy of the living body only during a 

portion of the locomotion cycle during which muscles of the joint would otherwise be doing work across the joint to absorb 

mechanical energy of the living body.

This element is infringed literally, or in the alternative, under the doctrine of equivalents.

For example, Defendant provides Amplify which is an augmented exoskeleton (“device”) for human legs. The exoskeleton 

comprises components including but not limited to a motor/generator, gait sensors, and a microprocessor. After strapping 

the exoskeleton to the user’s leg, in the stance phase (“during a portion of the locomotion cycle”), the motor/generator in 

the exoskeleton absorbs the kinetic energy (“mechanical energy”) and converts it into electrical energy when the breaking 

is performed by the joint muscles to decelerate the joint movement. It is apparent that the joint muscles would absorb the 

mechanical energy during breaking in downhill in the absence of the said exoskeleton.

Furthermore, human walking exhibits a locomotion cycle in two phases i.e., a stance phase and a swing phase. During 

the stance phase, the limb is placed on the ground to propel the human body in a forwarding direction. In the swing phase, 

the limb is flexed to leave the ground and brought forward to commence the movement.

1-c the device is 

disengaged during a 

portion of the 

locomotion cycle 

during which the 

muscles are doing 

work across the joint 

to increase 

mechanical energy of 

the living body and the 

absorbed mechanical 

energy is at least 

partially converted to 

converted energy and 

the converted energy 

is provided to one of 

an energy storage 

device or power 

consuming device.

Defendant provides the device that is disengaged during a portion of the locomotion cycle during which the muscles are 

doing work across the joint to increase mechanical energy of the living body and the absorbed mechanical energy is at 

least partially converted to converted energy and the converted energy is provided to one of an energy storage device or 

power consuming device.

This element is infringed literally, or in the alternative, under the doctrine of equivalents.

For example, Defendant provides Amplify which is an augmented exoskeleton (“device”) for human legs. The exoskeleton 

comprises components including but not limited to a motor/generator, gait sensors, and a microprocessor. After strapping 

the exoskeleton to the user’s leg, during the swing phase (“disengaging the device”), the joint is flexed and brought forward 

(“increase mechanical energy of the body”) to commence the movement.

Furthermore, the energy absorbed during the stance phase is converted into electrical energy (“converted energy”) by 

using a motor/generator. The generated electrical energy is used to charge the battery (“energy storage device”).

Upon information and belief, since the exoskeleton absorbs and augments energy in the stance phase, it is obvious that 

during the swing phase the knee muscles do not absorb the energy, hence, the device is disengaged for a portion of the 

locomotion cycle.
