Algae Blooms Protecting Our Future Water Supplies Report focus not only on categorize and review the recent intellectual property surrounding Harmful Algae Blooms (HAB), but it also mentions the technology that is being created to remove Harmful Algae blooms from water bodies due to increasing public concern about drinking water sources and environment. This report also talks about the patent trends and key players within the space.

4. OBJECTIVE
Harmful Algae Bloom (HAB)
This report was completed to not only categorize and review the recent
intellectual property surrounding Harmful Algae Blooms (HAB), but also to
bring awareness to interested people. It is designed to be read, skimmed or
for the viewer to look at only the parts of interest.
Algae Blooms is an area of environmental and public concern as drinking
water sources and other large bodies of water are increasingly
compromised due climate change and agricultural drainage. These factors
have increased the frequency of HAB’s forming in lakes, ponds and other
bodies of waters. The toxins from Harmful Algae blooms are of special
interest because they are often difficult to remove without special
treatments methods. Society is trying to meet the threats to these waters
using innovative technology.
Understanding what technology is being created to meet these future
needs is important and by analyzing patents we can determine interesting
trends and players within the space. In particular we are looking at IP
within the last 5 years and in particular with technology belonging to the
CPC category YO2 for technologies relating to climate change

5. SYNOPSIS
Toxic Algae Bloom (HAB)
Even though Algae blooms have been known for quite some time, due to
climate change, the water supplies have been increasingly compromised
due to recent weather changes, agricultural runoff the rising
temperatures. The patent publications over the last 50 years also
supports this by showing a steep and continuous amount of patent
publications beginning in 2004. In the year 2018 there were 385 patent
publications regarding this topic.
This report was done using a variety of programs and services. All the
patent searching was done in PatSeer. A full search was completed with
3784 patents found. From this search a core set of patents was selected
based on date (2015-01-01 to the present) and some selected keywords
derived from PatSeer’s advanced clustering. These keywords were
based on interest only with no other purpose or agenda. The final set of
1004 patents and is the set which the PatSeer Analysis tools were used.
Some Background information was also included on Pages 6 & 7 for
reference, but there are many more references and news articles
available for reading as well. This is only a small particular subset of
those.
