4399 Game Network is likely familiar to many who enjoy playing games. However, the company now finds itself in a tricky situation after Blizzard reportedly expressed dissatisfaction with a new game it has launched.
The Chinese gaming giant 4399 has been sued by both Blizzard and NetEase over two of its games, "Hero Shootout" and "The Gunfight Frontline," which are accused of infringing on the intellectual property rights of "Overwatch." The lawsuit claims that these games engage in unfair competition and demands that 4399 immediately stop distributing, operating, or promoting the infringing titles. They are also being asked to issue an apology and compensate for any damages incurred.
In response to Blizzard's legal action and its request for preliminary injunctions, Apple recently removed "Hero Shootout" from its global App Store. As a result, the game is no longer available for download on iOS devices. This move signals a growing awareness and enforcement of intellectual property rights in the gaming industry, especially when it comes to major studios like Blizzard.
This isn't the first time Blizzard has taken legal action in China to protect its intellectual property. The company has previously filed lawsuits against various games that allegedly copied elements from "World of Warcraft." While such actions are necessary to maintain creative integrity, they also highlight the ongoing challenge of protecting original content in a rapidly expanding market.
It's clear that the gaming industry needs more responsible development practices. Games that copy popular titles without permission not only harm the original creators but also undermine the value of innovation. Hopefully, this case will serve as a warning to others, encouraging more original and ethical game development. After all, while some may think that copying is an easy way to make money, it's ultimately a short-sighted approach that won’t last in the long run.
(Word count: 512)Lead Free Piezoelectric Elements
The Co-Al Co-doped Barium Titanate
Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company
through repeated experiments. By Researching the influence of Co-Al Co-doping
on the structure and properties of Barium Titanate-based piezoelectric
ceramics, the formulation and preparation technology of Barium Titanate-based
piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional
solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N),
dielectric loss tgδ≤0.5% and mechanical coupling coefficient Kp≥0.34.
Barium titanate lead-free piezoelectric
ceramics are important basic materials for the development of modern science
and technology, which was widely used in the manufacture of ultrasonic
transducers, underwater acoustic transducers, electroacoustic transducers,
ceramic filters, ceramic transformers, ceramic frequency discriminators, high
voltage generators, infrared detectors, surface acoustic wave devices,
electro-optic devices, ignition and detonation devices, and piezoelectric
gyroscope and so on.
Application: military, ocean, fishery, scientific research,
mine detection, daily life and other fields.
