ANDREWS, U.S. DISTRICT JUDGE
the Court is the issue of claim construction for the term
"central location" in U.S. Patent No. 5, 815, 488
("the '488 patent"). The Court has considered
the parties' briefs. (D.I. 435, 439, 443).
filed this action on March 10, 2016, alleging that Sprint
infringed the '488 patent with certain wireless services
on its LTE network. (D.I. 1). TC Tech asserts two independent
method claims of the '488 patent, both of which include
the disputed "central location" term. The claims
method for enabling a plurality of remote locations to
transmit data to a central location comprising the
at each remote location, coding data to be transmitted by
translating each group of one or more bits of said data into
a transform coefficient associated with a particular baseband
frequency in a particular subset of orthogonal baseband
frequencies allocated to the remote location, the particular
subset of orthogonal baseband frequencies allocated to each
remote location being chosen from a set of orthogonal
baseband frequencies, the subsets of baseband frequencies
allocated to each remote location being mutually exclusive
at each remote location, using an electronic processor,
performing an inverse orthogonal transformation on said
transform coefficients to obtain a block of time domain data;
at each remote location, utilizing a modulator to modulate
said block of time domain data onto a carrier signal for
transmission to said central location, said carrier
signal having the same carrier frequency for each remote
receiving at said central location from one or more
of said remote locations, one or more blocks of time domain
data modulated on one or more of said carrier signals;
using a demodulator, demodulating said one or more blocks of
time domain data from the carrier frequency signal [;]
performing said orthogonal transformation on said demodulated
time domain data to reconstruct said ...
