“Once we sowed wild oats, now we cook

Mining patents for useful information can be tedious. One thing you can do is
to look for keywords to use in Google® searches. For example, in a previous
post I listed a Breakthrough Technologies LLC patent with the following claim …
///////
Sulfur production
February 4, 2020
Breakthrough Technologies, LLC (Boston, MA)
http://www.btventures.com/
What is claimed is:
1. A method comprising: providing hydrogen sulfide into a first chamber
adjacent a second chamber; contacting the hydrogen sulfide with microwave
energy within the first chamber, the microwave energy generated by a microwave
source; providing the hydrogen sulfide to the second chamber, the second
chamber including an outlet and a waveguide, wherein an ultraviolet light
source resides within the waveguide of the second chamber; contacting the
hydrogen sulfide with ultraviolet light within the second chamber, the
ultraviolet light generated by the ultraviolet light source, wherein contacting
of the hydrogen sulfide with the ultraviolet light results in hydrogen gas and
sulfur; and separating at least a portion of the hydrogen gas from the sulfur
using a gas permeable membrane to allow the separated hydrogen gas to ventilate
through the outlet of the second chamber, wherein the gas permeable membrane
resides within the second chamber.

Equity Firms discovered as the result of a Google® search. The list focuses on
companies pursuing acquisition and development of existing resources. While the
list will be useful to many, this series of posts focuses on techniques you can
use to identify startups with promising new technologies.
So, on to the next step in the quest to find new technology on the cusp of
successful deployment.

Nothing Ventured, Nothing Gained: Follow the Lead of the Oil Majors
How do you identify startups that fit your corporate goals? One way is to set
up and advertise a venture capital unit, which enables young companies to pitch
their technology to your corporation.
And that is just what several oil majors have done.
Studying their portfolios can provide a wealth of helpful information, whether
you are a venture capitalist, a startup, or simply interested in identifying
emerging technology.

Searching Patents
Patents: Emerging Tech
Patents are a rich source of cutting-edge research. And much of the research
reported in patents never appears in peer reviewed journals. So, to identify
emerging technology in your field, consider searching the patent literature on
a regular basis.

Reviewing Patents
Searching for patents is iterative. You type in some keywords. Results reveal
more keywords. You type in those keywords. And repeat.
This can be really tedious, irksome even. Sometimes it is hard to figure out
whether a given patent is even relevant to your needs.
Fortunately, a number of experts have offered tips to make it easier to read a
patent quickly.

Patents and Run On Sentences
Per USPO rules, the Claims in a patent must be stated in a single
sentence. In many cases, the “single sentence” can be, thanks to colons,
commas, semicolons, et al., several hundred words long.
But remember that, as difficult as it may be to wrap your head around any given
claim, it still is faster than reading the whole patent.

Starting Down the Startup Path (Part 10 of a series): The
Bigness of Machine Learning
Big data is a big deal. We humans generate so much data that our puny
brains are unable to process it. So we have created machines to do that for us.
There is a whole discipline called machine learning designed to train these
machines to process massive amounts of data in useful ways.
“Machine learning,” as Serdar Yegulalp notes in an InfoWorld article, “is a
complex discipline. But implementing machine learning models is far less
daunting and difficult than it used to be, thanks to machine learning
frameworks—such as Google’s TensorFlow—that ease the process of
acquiring data, training models, serving predictions, and refining future
results.”

Thread the Needle
In a horse race, the goal is to bet on the winning horse. Common sense tells us
that if we knew for a certainty which horse would win the race, racing them
would be pointless. The same logic applies to new technologies, and the
companies that create them.
That’s why it can be useful to look at companies that have been examined by
investment funds like the Columbia Seligman
Communications and Information Fund.
