Recently, the State Intellectual Property Office issued the "Invalidation Request Examination Decision" (No.
The patent battle was provoked by Kingfa Technology
The patent battle was provoked by Kingfa TechnologyAccording to the "Invalidation Request Examination Decision" issued by the State Intellectual Property Office,
▼March 23, 2020
Kingfa Technology voluntarily applied to the State Intellectual Property Office for BASF's Chinese patent "Method for Continuous Production of Biodegradable Polyester" to confirm that all its patent rights 1-27 are invalid
▼ April 23
▼The State Intellectual Property Office accepted the request
▼ May 18
▼BASF responded for the first time and amended the claims
▼ August 12
▼BASF finally submitted a revised claim, which was reduced from 27 to 26
What is the impact of removing an ingredient?
What is the impact of removing an ingredient?How big is the impact of one of the main deleted claims and the reduced claim?
Industry insiders pointed out that BASF deleted the set of technical solutions based on "aliphatic dicarboxylic acids" in claim 1 (for the production process of PBS products), that is, some of the invalid solutions mentioned in the invalidation decision.
This means that the exclusive patent authorization of BASF obtained by Red Avenue New Materials has the advantage only on PBAT products, and PBS products will not have patent protection
BASF’s previous patents included two types of technical routes: PBAT and PBS.
Biodegradable materials competition between two companies
Biodegradable materials competition between two companiesDriven by environmental protection policies, the application of biodegradable plastics such as PBAT, PBS, and PBST in the fields of disposable tableware, packaging, agriculture, automobiles, medical care, and textiles is ushering in new opportunities for market development
According to incomplete statistics, the number of projects currently under construction in China has reached 4.
Both BASF and Kingfa Technology are stepping up their layout, taking degradable materials including PBAT as one of the important directions for their layout in the next few years
●BASF: Cooperation with local companies + 3 production lines in Zhanjiang base
BASF is currently the largest PBAT manufacturer in the world.
BASF's biopolymer Ecoflex® was launched on the market in 1998 and is certified as a compostable product according to the German standard DIN EN 13432 as well as the American standard ASTM D6400
Typical uses for Ecovio® are organic garbage bags, plastic wrap, fruit and vegetable bags, as well as agricultural mulch and food packaging

In addition, BASF will also build a PBAT production line in the Zhanjiang integrated base
●Kingfa Technology: With independent technology, 60,000 tons of PBAT was completed in the first half of this year
Kingfa Technology also has its own technology
.
According to public information, the PBAT patent that Kingfa Technology applied for in 2011 is a step-by-step method
.
Industry insiders said that this is different from BASF's one-step continuous method.
The difference between the two is very large, the production equipment is completely different, and the production process derived from this is also different
.
Most of Kingfa's PBAT products were previously exported to Europe including Germany, and the export value accounted for nearly 70% of the industry
.
The company currently has a production line with an annual output of 71,000 tons of fully biodegradable plastics, and is building two new production lines
.
Among them, the PBAT production line with an annual output of 60,000 tons is expected to be completed in the first half of 2021, and the PLA production line with an annual output of 30,000 tons is expected to be completed in the fourth quarter of 2021
.
In the first half of 2020, Kingfa Technology achieved sales of 31,400 tons of degradable plastic products, a year-on-year increase of 49.
28%, of which the domestic market accounted for about 20%, and product sales ranked first in Asia Pacific and third in the world
.
With the gradual completion of the company's biodegradable plastic engineering projects under construction, the company's profitability is expected to continue to improve
.
In 2017, 2018 and 2019, Kingfa Technology achieved sales of 17,000 tons, 26,000 tons and 48,000 tons of fully biodegradable plastics, up 147%, 54%, and 84% year-on-year, respectively, and its product gross profit margin was much higher than Modified plastics have become the company's second largest source of chemical material revenue
